I wouldnt mill the head or block that much. If your not happy with the 7.47:1 compression with the standard 137mm rod with a y8 headgasket, look into the FJT custom length rods. That will bump it up to the 8.4:1 range with either a .030" HG or the y8 headgasket
Well the h beams r from fjt i have to get this up and running asap so least amount of downtime so i went with the hbeams. So just with that said whats ur take on it then how much on either should i have to go?
