Is it possible to lift a head gasket with only 6 psi of boost? Took the head gaskets off car and they looked ok. But they were the graphite gaskets. The middle row of bolts were tight but not as tight as the bottom set. Could have this caused it to lift? The shop that did my head and cam swap does NASCAR motors just wondering if they messed up because everything else looks ok. Had heads checked and they checked out fine. Block was checked also it was fine. Thanks

 

What makes you think you lifted the head, did it do anything it wasnt supposed to?

 

I had white smoke out the exhaust.

 

Did you use the same head bolts ??? was it fresh and smoking ?? maby a scrached cilender wall

 

How much rwhp are you making?

FWIW, I've reused cometics on my 422....they had low miles though, and looked ok. i would not recommend though.

 

I bought new ones but at the time I hired a local shop to do the work! The bottom bolts were very tight middle ones were not that tight I turned them without help. I'm thinking they used troque for ARP bolts instead of GM bolts. I now have head studs to put back in it!

 

If you can turn the bolts then you have problems. You need to get new bolts, or better yet, get some arp head studs and tighten them down to spec. I doubt you damaged anything if it's still running fine off boost.
