Decking block cost??

Not even close - a bone stock, uncut block with wisecos and 7.005 rods is within .005 of 0 deck. But your advice is correct. DO NOT CUT that block if you are running aftermarket rods and pistons.

You are going to have a serious compression problem - what is your head CC now?

well again your number is SPEC, these blocks are off as much as .050 off blue print (+/-). ive seen stock pistons anywhere from .125 to .250 in the hole lol...
