Having trouble sealing MLS head gasket using Apex MLS and Victor Reinz bolts. I am rebuilding 2nd 1uz for boost using ARP and Cometic MLS. My mechanic can not figure out why Apex MLS blew on start up BEFORE boost. Milled head and block. Has anyone had problems sealing MLS gaskets? Should I be using copper spray? If the machine shop didn't have proper RA, would that cause the problem? (small town machine shop- probably doesn't know what RA is)
Keep blowing headgasket on N/A 1uzfe

I lifted the heads on my engine with MLS gaskets but it was running 21psi and a poor tune.
Rebuilt the engine and didn't re-machine heads and it ran until sold without any problems/
I used ARP studs.
