head gaskets Trying to figure out what head gaskets to buy. I have a 99 z28 but it dosent have the original block in it, i bought one from TSP. I keep seeing the head gaskets for 97-01 and 02 and up and only difference i know of is the thickness. Dose it matter which ones i use
I have cometic .040 MLS gaskets and i gave them a light spray with permatex copper spray and they seemed to do the trick just fine. They made a great seal and on the plus side are reusable.
I would guess a MLS gasket will not blow out as easy as a graphite gasket which is a good thing if you are making a lot of power.

I use Cometics. Like Brad said, a little copper spray and no leaks. If you want to increase compresion and reduce quench, go with an .040 or .045 Cometic. If not, I'd just go with a stock MLS gasket.

I thought that there was a recess or some small difference between the 97-01 heads & the 02 + heads. That may be the main reason for the different specified gaskets. With your LS6 style heads, the 02 & up GM gaskets would be the proper fit if you choose a GM gasket. I'm also a Cometic fan & agree that a copper sprayed (both sides) .045" Cometic is a good choice. The sponsor you buy from can also confirm the proper gasket for you. Good-luck
