Valve Clearance

Aaron Majcan said

I had 1.848" compression height pistons in it already that came with my block when I bought it and it put me 0.090"down hole at TDC when installed them. I found 1.92" flat tops that will get me much closer to zero deck. I didnt think to measure my piston clearance before I pulled them out. Rookie mistake.

No disrespect, but most of us here have found it necessary to 'deck' a block in order to achieve the desired deck height. ..just the way it goes. In fact, you'll end up with a much better product when finished, cause in many cases, the block is out of square or some other crazy anomaly. As well as having a better surface for head gasket bite.
BUT, this is only done when you know what pistons, rods, and crank you will be using.
