What head gaskets for 243 head swap on 98 ls1
I know this May have been asked times before but I can't figure out because of conflicting answers.
So I need to know which head gaskets to use on a 98 stock ls1 Vette motor, putting on a set of 2002 243 heads do I use the gaskets for the ls6 or the ls1 ??? Keeping in mind the years of the two different parts.
Thx

As mentioned, the 2002+ LS1/LS6 MLS gaskets will be correct. The older LS1 heads have a notch that requires the composite gasket to seal the coolant passage.
I would use a .040 Cometic gasket to bump the CR by .3 if your planning on a camshaft.

You are also going to need the valve covers for the new heads. If I'm not mistaken, 97 and 98 had perimeter bolts and all the later had center bolts. Correct?
