Great video, just a small note, Jet-Hot is the original ceramic exhaust coating and we coat, new and pipes all the time. Many people have their new header shipped straight to us (even if they come with a cheap OEM ceramic coating) to have us remove the cheap paint/coating and re-coat with our lifetime warrantied coating.
Great video. Just as a heads up. When reading with an IR temperature sensor you have to take into account the emissivity (how much radiation is emitted or reflected) of a material. Ceramic coated headers have a low emmisivity (very reflective to IR). This means that when you measured the ceramic coated headers, the temperature was so low because you were actually measuring the surrounding (reflected) temperatures.
This is almost right. The low emissivity of the polished ceramic (like offered by Jet-Hot with classic polish) actually reduces the emitted radiation (thus the word emissivity) as the metal gets hotter more and more of the heat energy coming off the headers is infrared. if you painted a black stripe on the ceramic header that strip will actually throw off more heat in that area.
I have been told that the best thing to do is buy plain headers and sent to jet hot to have them coated. Typically you get a better coating when u send them out vs buying them already coated
I'm sick of burning wires so ceramic coated headers are what I'll be doing next. I had them on my pontiac gtp and remembered turning the engine off and being able to touch the tubes 2 mins after I turned the car off
I have an 82 Shortbed with a big block as well! I also bought the Summit brand headers which are very well built! I am going to clearance the flange for the ARP studs. My question is do I have to dimple the tubes for clearance on the frame? The old headers I took off had dimples where someone hammered on them on two tubes on both sides. I really don’t wanna hammer on these being so nice and all! Thanks in advance!!
TruckandRoll no sir! I’m excited. I’ll prob install my fuel cell tomorrow and run my fuel lines and be ready to drive it by the weekend!! Thanks for the reply!!
That Hooker must have been their cheap header for lower market. Every hooker i have ever seen has a completely flat and very thick mount flange. I just threw away a set of bbc Hedman header that has the exact same issue with the mounting flange surface as you just described
Wow this is completely random that I was looking at summit racing headers for my c10. Decided to look on youtube for a review and ran across this literally almost the same day it was posted
Best honest youtuber i ever meet you help me alot thanks for your help in instgram also the info that you give us in your videos i am building my 454 from your idea thanks agin i got same top end kit also i got the same headrs i wish you best& goo luck in your life bro 💙💙💙
You didn't check Temps the same way and then you checked the painted surface on the floor vs the unpainted surface. You used the click to check 2nd time while 1st time you used continuous check. Not sure on exact verbiage
@@adrien2323 I was gonna do a video of temp differences from factory manifplds to ceramic coated long tube to ceramic coated with header wrap long tube, but I got lazy also 🤣
Richard Reid i feel like it should help a bit. The intake air temps should be lower as well also. The way i got my big block to run cool was a combination of dual fans, cooler thermostat, and working overflow tank.
Since the ceramic headers keep the heat contained in the exhaust gas, everything after the header (cat, muffler and etc) should be hotter with a ceramic header. Not sure what the full impact of this would be, but at a minimum the heat shields over the exhaust pipes will become more critical.
Yea thats true. Remember too air is a good insulator. I wouldn’t go too crazy with heat shields/wrap if you can keep at least 1” spacing from wires and other components. I guess one potential caveat would be fuel lines due to the safety risk there.
Honestly it couldn’t hurt but is likely overkill. Downside of header wrap is typically corrosion beneath insulation. However the ceramic coating may also do a good job of protecting against that. Id say you dont need to do both unless you truly want to.
This is awesome you are the only person on RUclips I can find running the same Edelbrock topend kit that I bought. I’m interested to know if you are producing enough vacuum for your vacuum assist brakes.
Nice! I had the same issue when trying to research this kit before I bought it. There are absolutely no issues with power brakes with this kit. I’m not sure how much the Holley Sniper affects this vs a carburetor since my system controls IAC and timing so I’m able to run a decent amount of timing at idle which should generally improve vacuum
@@truckandroll989 Quick question, did you have any plug or wire issues with those headers, I noticed that your wires are run real nice and they clear pretty good but was that your original set up?
@@everydaylife1885 I bought the wires from MSD that you make yourself which helped with routing. I didnt have any issues with these since the ends of the leads are bendable so you can angle them away from the header primaries. That being said they sell these sock looking things which you can slide over the ends to protect them better.
@@truckandroll989 Ohhhh, that makes sense, I was thinking "I never seen a set of wires like that before", custom, good idea. Right, I was thinking about those little sleeves also but I would like to try that wire set up, thank you for that
To my simple mind, it is hard to believe that on the day when the ambient was 99F, and he measured the ceramic coated header to be only 30 to 40F more!!! Then he measured the internal floor and they only differed from 125F to 119F. First day ambient was 69F, 2nd day 99F.
@@truckandroll989 fax, tbh tho hooker headers arnt great unless your car is only for the drag strip. My grandpa has his old hooker header (looks like a big bulge of twisted and looped tubing) poking out right behind the front tyres and they don't do to well at low rpms.also hooker headers shine above $600 so these are much better for the everyday driver
Depends on fitment and whether you care about 30, 40 or 50 extra ponies up top. On a street car torque is more important than hp especially driving on public roads.
Lol you should went BBC Ceramic vs Hooked Ceramic w both headers same idolize. Example 3" headers Your trying to go A vs B. Should been 2 same type headers vs differ brands
Ceramic coated headers are definitely the way to go, especially for a daily. Reduces heat tremendously!!!

Awesome , Amazing the temp differences. something many have never thought of. Thanks for the great info.
Excellent video. Temperature under hood was the reason I spent the money on ceramic coated.
Very informative! Thanks for taking the time to get some real world values.
Thanks for the info bud. Just sent all my headers and turbo manifold out to get polished ceramic coated by final finish in Kentucky.
Nice!
Thank god i just bought the ceramic summit headers. This is good to know!! Thanks man!!!

Absolutely correct.. I/r thermometer readings on reflective surface of exhaust are irrelevant.

Great info, I always new their was a difference in temp between the two.. but dang not that much. thank you.
👍.. I ordered the Summit Ceramic Headers today. Glad I made a good choice. 😃

it makes sense that the intake is higher temperature. The heat doesn't go out through the headers, so its gotta go somewhere.
Great video thanks!
Excellent video. Thanks.
You’re welcome. Thank you for watching!
wished i would of saw this a couple days ago i just ordered those same summit headers but just painted for my c10 454 that im building!
Decision made!! Best video ever

MDG TX nope no dimpling necessary. Mine fit great :). Thats awesome on the 82 ! Dont see a ton of squarebody big blocks around anymore

@@adrien2323 I do understand how you can make simple mistakes like that if you don't go back and look at how you did it before
U think the overall cooler engine bay help with coolant temp possible run a bit cooler
Richard Reid i feel like it should help a bit. The intake air temps should be lower as well also. The way i got my big block to run cool was a combination of dual fans, cooler thermostat, and working overflow tank.
It will help a lot. Anywhere you can reduce heat helps keep things running smooth

What are you thoughts on ceramic coating in combination with header wrap?
Honestly it couldn’t hurt but is likely overkill. Downside of header wrap is typically corrosion beneath insulation. However the ceramic coating may also do a good job of protecting against that. Id say you dont need to do both unless you truly want to.
Jet hot is by far the best ceramic coating, service and quality

I am using Edelbrock’s Proflo 4 multipoint setup that controls timing as well
I wish they made these to fit a 70-72 nova 454

Both great headers but I choose newer Hooker over BBC any day.
Plus Hooker Longtubes headers hugs up in chasis tighter n not hang so low
Idkn what your saying but i dig your enthusiasm my dude!
@@truckandroll989 was typo.
Hooker headers- when only the best will do
Lol let me tell you. These summit headers are honestly quality
@@truckandroll989 fax, tbh tho hooker headers arnt great unless your car is only for the drag strip.

Should have left a painted header on one side and put a ceramic in the other .
Smaller diameter wont help at the low end, thats a common myth. Headers help over the entire curve fairly uniformly as shown on countless dynos.
Depends on fitment and whether you care about 30, 40 or 50 extra ponies up top. On a street car torque is more important than hp especially driving on public roads.
The ceramic coating will eventually flake and the tubes will rust. Looks like hell. I’ve had three sets that all did that.
Dang that is a bummer for sure. Truck is now with a new owner in Colorado. Hoping its holding up nicely for him.
Lol you should went BBC Ceramic vs Hooked Ceramic w both headers same idolize. Example 3" headers
Your trying to go A vs B.
Should been 2 same type headers vs differ brands
Aron Rogers 🤨
Ill take that as a compliment
@@truckandroll989 😁
The differences would be marginal, both are much gooder than oem manifolds.
