Head Gasket Question

I just bought a set of 5.3 862 heads for my stock LS1 (yr:2000). I need to know or find out the part number for .40 thick head gaskets for these heads onto my block.

Thanks

I bought factory MLS gaskets for my year model and everything worked fine with my 5.3 head swap.

GM doesn't make a .040. Fel pro does though and it is a lot cheaper than a Cometic.

Is the Fel-Pro graphite? If so, I'd hate to be the one scraping the block the next time the heads are off! Haha!
