Does any one know if the stock head bolts are TTY?

Also, anyone have any input on the best head gasket to use?

 

ive heard that the napa brand gaskets are of upmost quality... i like felpro... never had a problem with them and the price isnt bad...

i dont think the head bolts are TTY..i know the kegger bolts a TTY but im not possitive..

 

The Magnum Engines book says to use new bolts, but it doesn't say anything about them being TTY.

There is a specific sequence they need to be tightened down in. And the torque numbers are 50ft-lbs, then 105ft-lbs, then 105ft-lbs again.

 

here is a stuped question whats TTY?

 

Shott- felpro it is

Yeah the book says to repalce bolts, but does not mention whether the originals are re-usable. I am talking about replacing heads with moderate use, so, Am i going to get good torque results replacing the heads with the same head bolts

 

TTY= Torque to yield. In other words, this is the new age engineers' way of foregoing a lock washer or teflon nut. The plan is that when the robot drives a bolt in to a specific torque, that the stretch whithin the bolt acts as lock. It is common knowledge that the intake bolts are tty because, being a major flaw of the magnum motor, intake bolts are commonly bought and sold. The heads have a sturdier/beefier gasket. I am hoping to re-use those bolts

 

gotcha...... stuped engineers lol (i probley shouldent really say that) i would much prefer a locknut rather than stertch the bolt lol
