Bought a complete built LS3 for a customers car. Here are the specs. Was told from the seller the last owner put the long block together in his garage but the Bottom end built professionally. Not that I don't trust anyone but when doing a customers cars I want things to always be right. Going to pull the heads and have a machine shop inspect everything. Going for close to 900-1000 HP on this build. Did a quick search on the forums but came up blank. Can someone who knows just shoot me a good head gasket to run. I have heard some feedback on the cometics. Just want to hear a little more before I order some.

They sound like a great deal. The Description is scaring me a little bit though. "These GM Performance head gaskets feature stainless steel faces recommended for stock and mildly modified engines. They are available for many applications and several thicknesses"

This engine is no where near stock and is going to be quite a bit past "Mildly Modified" pushing 20+ lbs of boost. Have you used these on your Turbo engine with no problems.

Many people using them, even on small bore stuff that the gasket dwarfs the bore.
