Cool deal. Thanks for the info
I don't like that 1041 gasket from Felpro because it's SO thin. Most aftermarket pistons are setup to be .008 to .010 outta the hole which makes for a very small squish area with that gasket.
Stock gasket should be OK.

I agree, it don't pay to get below a quench area of .035". But on the other hand if you are gonna use power adders you need the Felpro for the reinforced ring and body.
