I like to leave my deck .010 or .005 above the pistons.
I get my blocks rough bored then take them home and install the crank and 4 corner pistons. then measure each corner for how much needs to be cut off. then I take it back and the machinist puts it in the machine at the correct angles for my parts. If youve got one corner way of sometimes switching pistons, and or rods around helps get it more even.. I was going zero deck but once came out with pistons out of the hole, could be my fault could have been his no way to tell!! but lesson learned.
For my very last motor another shop told me that was a waste of my time and I didnt argue, they must have had a better way of measuring because I asked for .010 and got .008-.011 on the corners, very close and less hassle.
I have been running copper head gaskets for the last 5 years with great success they come in .031,.041,.043,.050,069,.090. They are re useable, and will help fix a block if its decked to much as happened to me. they are about 70 a set from summit, so they cost the same as good head gaskets except you can re use them over and over.
I dont like angle milled heads at all, did it in high school years ago and unless the intake is done also It cant be a good thing. Rounding the holes to bolt the intake on, then who knows where the gaskets end up?
Thats what I do to my stuff, youll get some far more technical answers from experts Im sure, Im just a poor racer who has to do as much as I can myself, and its worked out.
