LS3 S/C head gasket failure? My Centrifugally scharged LS3 started to overheat and makes pressure to cooling system after harder pull. Coolant coming out of reservoir and lots of air in radiator. So somesord of failure.
What is most typical issue in these? And known fixes. Didnīt find much with search but there is little language barrier...

Not much boost. 7-8psi normally. 730fwhp/870nm with e85.
recently swapped from 6-rib to 8-rib belt and pulleys and boost had raised to 10psi and didn't notice it right away. probable cause for damage.

Lift heads? meaning head quench/disort? (or how do you say it). Or back up from head bolts?
Iīm going to order gaskets and bolts now, lets see what else needed when i disassemble engine.
Thsese should fit? right?

What about fasteners, bolts or studs if nothing needed to bottom end?

Because of cylinder pressure and/or tuning issues the heads will literally move away from the block.
What head gaskets and head bolts or studs are you using?
I would post this question in the forced induction section. You will get a lot more response from some really good people.
