914-4, stock crankshaft, Stock Jugs, H-Beam rods, JE Pistons, 7k redline; how tight can I safely go? I've heard that a deck height of 0.050" is a safe amount. Can I go 0.040" without risking interference issues?
Thanks, Jim |

I read here somewhere that the deck height requirement was greater than ~0.028 which keeps the piston from hitting the flat portion of the head when the pistons reach max temp.
That seems pretty close to what Chris said. Attached is a file I got from someone here on calculating shim size and compression ratios that may or may not be useful.
