LS1/LS6 Head Gaskets Well I'm struggling with this one.....I'm putting on LS2/LS6 243 castings on my '99. Do I buy head gaskets for the '99 block or the '04+ heads? They are definitely different part numbers....The older ones even have different part numbers for left and right. GM has a kit with two gaskets for the 97-01 and two different ones for 02-04 in their performance parts catalog.....
Just struggling with the decision.....
HELP!

This is quite thick actually. They dont have a .040 or a .042?

Thanks for all the replies. I've read some questionable things about the Cometic MLS gaskets.......Sooo I think it's the newer 12498544's for me!
