6.0 heads on LS1, what head gaskets do I need? I have 6.0L (317) heads on a 98 ls1, and I want to go with gm mls gaskets. Are LS1 gaskets the same as the 6.0 gaskets or is there a difference?
Thanks
Brad

6.0L MLS gasket GM part #12589227 in case you needed it.
And they should do just fine. I'm using them on my current project which has a 101 attached to it. Not running yet but we'll see how they hold up.

I'm in the same boat, but The heads I've come across are fully ported. I'm still a 346ci, would fully ported 317's be a good idea? sorry for the hi jack 
Also can you pull the heads off in a car if you go studs over bolts?
