Block Questions....
I pulled the heads off my car, and the noticed that block is rough. I was told that I have a pre-2001 block and the block is supposed to be rough.
Now I dont think anyone would disagree that a smooth surface will seal better than a rough surface.
Should I pull the motor and smooth the block... or should I just get new gaskets and call it a day?

The surface is supposed to be rough to grip the head gasket. Different gaskets require different block and head finishes. Consult the head gasket manufacturer. I would jsut clean up the surface with a plastic scraper and solvent and assemble with new gaskets. Is this a built motor? Are you building it? For 20+ psi, the heads and block need to be surfaced.

The block is a built bottom end.. but I lifted the heads on the dyno when I was trying to push it to 30#.
So... when we removed the heads (heads are okay)... we broke 2 retainers, and lifter. ... I am going to o-ring the heads. but my machine shop is telling me that I have to deck the block to get that 'roughness' out of the block to get a good seal.
Please advise.
