Nice to see I'm not the only one using a drill for porting. I feel I get a better cut using the slower speed. Perhaps I'm dumb but I think the water flowing easier will have less resistance to the water pump. Little things we don't really think about add up to horsepower, longevity, or efficiency. Keep up the awesome work Terry. Thanks for sharing.
Thank you for this "Cool" tip, Terry. Just to let your viewers know, the jog shape of the water ports and the bolt on either side of the 385s are meant to prevent head gaskets from failing. This is even more evident on early factory 351W heads and intake castings. Here, the water ports are actually "L"-shaped rather than the traditional rectangle and are also clamped by two intake bolts. Ford engineers deemed this arrangement to allow the ends of the cylinder heads/gaskets and corresponding head bolts to run cooler. Whether this was successful engineering is up for debate. Many subsequent Factory and aftermarket designs dropped this design. I've never had issues with either design but have only built N/A engines with safe over-bores and compression ratios of no more than 13.5:1.
Hey bill from what I've seen ford did more experimenting not being sure half the time if something was good or bad but I've never ran into any problems with any of their designs, thank you for watching and sharing your knowledge with us, I wouldn't know what to do with 13 to 1 compression oh wait a minute maybe I would I'd pick out the cam I want 😂😂
Every bit helps. I did a similar thing on a brand new intake for the same reason. Water passage needed just a little help to be quite a bit better. Besides....that 460 has gotta get some love while it waits!
Hey jd I'm doing good thanks for stopping in and seeing me i hope you and the family are doing well my son Adam is doing some videos you may like aluminum heads on 302
🔔😎🇺🇸 Id maybe gasket match and not make it so narrow next to the bolt hole. JMO. On SBF Ive never had an obvious temp problem at the thermostat. Never know about isolated hot spots... SBChevys are bad. Old Hot Rod Magazine article by one of the SBC designers he says ... most of the factory SBC heads have up to 13 dead circulation hot spots in the head's coolant passages. Thats why you must have high pressure and high volume pumps and a thermostat or restrictor. To cause back pressure in the heads to stop steam pockets. Thats why aftermarket alum heads cool better. Not because theyre alum but because theres no bad spots. Actual temp at the thermostat is an average not an indicator of idolated hot spots. 🤔🤔😎 Long winded... 😐 BTW. about 8 yrs ago my son put a mild 351w in a car. For the test drive he stuck in a thin alum radiator from a V6 Ranger and no shroud. 8 years later its still driving even on 95* days never gets over 185*. FORD !!
Stones don't really work that great on aluminum your best bet is to use a 40 or 60 grit sanding roll or a carbide bit when it comes to grinding aluminum , hope this helps you out and thanks for watching
The heads have water jackets at both ends but the intake only has jackets at one end. I drill and tap for a fitting to draw coolant from both ends to double the circulation.
That also reduces water flow going forward through the heads. The gasket holes between cylinders are small and there to prevent air lock and hot spots, not for major circulation. You want all the water flow moving forward around the chambers as possible. JMO 😎
@@hotrodray6802 It doubles the water flow through out the head. My big block cools more efficient with the exit out both ends because the coolant comes from the block up the middle as well. Not an opinion just fact.

All my reasons for doing this appreciate you watching and I do use lower speeds myself
That's really nice Terry.
Cleaned that up nicely.
The manifold looks great.
Can't wait to see the truck run.
Have a good evening. 👍🇺🇸👍
Thank you Ed, it's always a step closer I'll be happy to see this engine all back together, thanks for watching my friend
It's all the details that make the difference ....thanks Terry
Thanks for watching Bob 👍
I did my 4cyl a coolant temp went down 9f with same thermostat.
good video Terry. You are right, everything adds up and the little things do matter
Hello Jeff thank you for watching I appreciate it
Great tips! Anything that increases engine efficiency is worth doing
Thank you I appreciate that little things I think help make a difference, thanks for watching

@terrygrover6440 Terry, you should try 13:1 sometime. You'll like it! BTW, I haven't run anything that high since the Pro-Stock days of the 1970s.

You know all the little tricks Stuart, appreciate you thanks for watching
Awesome video Terry!!! That’s a good tip!!! Hope your doing well!
Hey jd I'm doing good thanks for stopping in and seeing me i hope you and the family are doing well my son Adam is doing some videos you may like aluminum heads on 302
@ oh I do like some aluminum heads on a 302! 😂 I’ll have to check it out!!!
Good tip thanks for sharing
Hi jim thanks for watching I appreciate it and commenting
When using burrs try wax or trans fluid to coat burr when grinding to keep clean from clogging up.
Sometimes I do depends how much grinding I'm doing, thanks for watching
Nice upgrade terry that is something overlooked a lot
Yeah it can't hurt from how I see it , thanks for watching appreciate it

Terry, I am a newby and would like to know how you keep the stones from loading up with aluminum ? THANKS - keep up the good work!

Obviously a bachelor as it looks like he is porting an intake in his dining room!
No just an understanding wife who knows I have to get things done 😂thanks for watching
Great idea. I think it's time for you to upgrade to a video camera and a tripod.
Hi buck I just do what I can with what I have i make nothing off of these videos just giving tips to the guys out here , thanks for watching
No more music?
YeeeHaaaw!!!
@hotrodray6802 I have no way of doing music right now unfortunately maybe in the future if I can
