340 street build help from experienced input

I use this cam with 1.6 rockers in a .030 over 360 with slugs at zero deck height and a .028 Cometic head gasket and trick flow heads. TTI exhaust stem to stern. A 904 & 3.55’s with 26 X 10 tires.

So you run a .028 head gasket with flat top pistons and closed chamber heads?
