What would happen if the head is over torqued?

 

You **** up the bolts and the block. There is a reason that they have those specs, stick to them to avoid the bad ****.

 

why are you worried about the head not sealing? you did listen to me and torque in the proper sequence and increase by 5-10 psi over multiple passes right? Like if you didn't it might not be a big deal at all, but it also might leak like a sieve. OTOH you are too farr along to look back now, and just finish it up and fix any leaks and whatnot at a later date.

 

If you dont properly torque the head you will take a chance of warping it warped heads are bad, a new HG wont fix a warped head.
