oh ok yea i have a buddy who wanted to torque his 12v bolts down i talked him out of that as soon as i talked to my local go to shop they said they have seen about 10 people try this 8 failed miserably 1 lasted till 45psi and blew then the other went to 60 and is still running as far as i know but 1/10 is not a good enough percent for me to try on my truck.

Yeah, we tried that, and under WOT I had coolant dripping down the front of the block/head. About 50psi boost. Once we installed the studs, no more issues. THis tells me the stock head bolts were allowing the head to lift off the block and leak from the front left passage, what would you say? BTW gasket was in perfect condition. I understand if you were just kidding, but just in case, I wouldn't want anyone to think they can get by.

I don't know We used the circular sequence starting in the center, then going w/ 4 tq increments, then heat it up shut it down and re-tq.

bolts vs good studs thing is a joke...lol.
Those trucks are ten seconds because the weigh nothing...not becuase the hp is high.
I thinking max boost of 50-60 psi and a little nitrous is NOT that hard on a head gasket vs 85 to 100 plus psi the big hp people are running.

And as far as bolts vs. studs they are a couple guys around here running s300/s480 twins with the Garmon sequence on stock bolts and holding the head down just fine and these guys are hard on there trucks. Would I do it? No, I have ARPs, but like I said a lot of guys around run it on high hp, high boost engines with no problems.

That is what a good cam matched to a good port job and proper tuning can get you! (Of course, I know you know that, Christian; this is for the digestion of the others here).
