Bolting on the heads
Now here we have a nice little chart that shows the head bolt torqueing sequence.
Now a word to the wise.
The 1st stop is shown at 20 Lbs. BS, not gonna happen
Spin all the bolts in snug with a speed handle.
Now take them down in the sequence shown to 25 ftlbs.
At 25 they will hold there and not keep moving.
Now take the complete set through the sequence to 50 ft lbs.
Run through a second time to be sure they are all holding at 50 ftlbs.
Now go through the sequence and give each bolt 1/4 turn more.
This is a 90 degree turn on the bar. I like to mark each bolt head as I do them to make sure I dont miss one.
Now, the part they dont tell you.
Take your torque wrench and starting at number one (1) bolt pull the wrench up and see at what point the bolt will just start to move.
My experience shows this to be at or around 100 ft Lbs.
Go back through the sequence and check each bolt as you carefully ease it up to the 100 ftlb or so mark.
You will likely find that one or more bolts will fall short of the 100 ftlbs.
I have found the some of the first ones in the sequence will be a little light on the torque after the final 1/4 turn.. (75 ft lbs or so)
With the DaHooooley engine the RH head using the MLS gasket from Cometic displayed a whole different feel upon torqueing.
The last 1/4 turn was a BITCH and I really had to lay into the break bar to get it.
This tells me that the Felpro gaskets are compressing a lot and that last 1/4 turn is causing things to move a little more.
All the bolts felt real good at 50+ pounds but after the final 1/4 turn things did move some more.
Just a good thing to do that final check and be sure all the bolts are the same torque.
I have never been a fan of the TTY bolts. There are several companies that make regular bolts for the 6.2/6.5.
Also there are stud kits available too.
Main issue is to be sure your bolts are all even.
one bolt that does not come up to par can cause issues.
This can be a leaky gasket down the road many miles or also an area of the block that is not under the same stress levels.
I have always just used the chart and done the 1/4 turn thing, Hmmmm seems that the tried and true stuff from the General is not perfect
Hope this helps.
