You were giving that breaker bar all it wanted and then some...thought it was going to snap there for a minute
Thank you for stating where the 2 short bolts go. (Each side was different when I took mine apart.) It took me a long time of video watching till I found your video!
Last time I installed heads on my small block chevy , I never used a angle gauge , torqued em to spec , never had any issues with my motor ran perfectly , just sayin.
After the first torque pass sequence of 22ft lbs did you make another pass with a higher torque value?
Thanks!
Just for feedback...
The first four videos in this set were quiet and relaxing.
This one was jarring at points with the addition of the music.
All I got is speed square. Wish me luck
Does the torque pattern pic you showed go for both sides
How many torque pounds the second go around
I have 10 pairs of vortec heads, all cracked, so i went with aluminum rather than 305's
Can you use the same bolts?
Quick question why are you using two different torque wrenches this video?
What is the cost to rebuilt the heads? Thanks
I hope you used some brake cleaner to clean that grease out of your threads if not you're going to throw your torque value off
Hey brother, thanks so much for this video series, it was a big help on my head job!
I have a question. I bought a brand new quinn torque wrench with a built in angle system to do the job. After you reach the angle you want, it tells you what torque you reached. I cleaned the threads the way you did too.
I torqued both heads, but what's been bothering me is the variation in all the torque values I got after completing the angle adjustment. I know the ultimate goal is to reach a certain stretch right? Also there's the fact that it's impossible for me to be consistent with a wrench that beeps at me versus one that clicks haha.
I've read in other places to verify torque after finishing up, but how the hell do you even do that? Any help would be appreciated.
I would like to know this too. Torque sequence seems pretty straight forward but I get confused when the torque angle gauge gets pulled out!
@@davegibson3763 hey Dave, so after extensive research, I found that getting different torque values is not uncommon. The whole point is to reach a certain amount of stretch in the bolt via the torque angle and sometimes, as I understand it, it happens at a different torque value for each bolt. So you may have a slightly different torque value, but you're achieving the desired stretch. Using the torque angle method, you eliminate having to account for variations like running torque.
@@davegibson3763 also, I didn't verify anything because I didn't want to risk over torquing. I just followed the instructions and my trucks running well.
@@asteriosanagnostou3243 Would it be ok to just omit the angle gauge and just make another pass at a higher torque value?I read a comment a guy made a couple years ago on this and said he didn't use the angle gauge it and it worked out ok!
@@davegibson3763 yeah probably. I've read the same. Hell I did my first heads the same, but the difference was the bolts. Newer ones, I don't remember what year they started, we're designed with strech in mind. But you're right, I've read many people doing it both ways and it working. I guess, the torque to angle is more accurate when It comes to clamping force.
Let me ask a question I got my heads on n everything can I just tighten my push rods make sure there's no lasg n I'm good ?
There is a video on youtube that shows a guy go through all the necessary steps to get the push rods just right!
Torque scene shows going passed 90 degrees what's the deal
Chevy says 90’ up SBC is 3 stage torque. 1st: 25 ft/lbs 2nd: 45 ft/lbs 3rd 65 ft lbs.
Where did you get this information for the torque angles? I know the LS series is like this but not the older 350s.
The vortec truck motors from 96-99 have torque to yield bolts. I just removed my heads from my 97 and discovered this. Not sure why but I was wondering if I could just put the standard bolts in and say screw that torque to yield stuff Lol!!
You can put ARP bolts in there and do that.
Could you put a head on the wrong side of the engine
Or is it just going 65 degrees
Very nice video,thanks;
(How do long extensions change the torque values on the torque wrench? ---They don't).
edit 5:50 the torque wrench does not get affected; the angle meter,yes, that is a bit sensitive to flimsiness of extensions; just use a sturdy 1/2 inch extension, 6 or 12 inches long.
I was told an extension will affect the torque because the extension will twist. Just sayin 🤔
did you ever use a torque stick for lug nuts
@@knockdolian12 tell me which factory manual says that!! or specifies a short extension! NONE
it does NOT matter if it twists; if it does not break,the torque is te same,nuff said.
@@joefreeman5580 that is a different thing; it´s a torque multiplier, that is not what we are talking about here
@@josepeixoto3384 That’s me told. Thanks 👍

King James Version
1 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;2 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;4 And that he was buried, and that he rose again the third day according to the scriptures:
Que Dios nos perdone.
