Running the numbers in my setup has an IVCL of 33.5° ABDC @ 0.050 and 61° ABDC @ 0.006. Static compression calculates out at 9.41:1 and Dynamic is 8.36 as calculated by Silvolites calculator. Heads are right at 62cc even though they are 64cc advertised, guess it has to do with the valve choice. I am cranking 180 psi at 700 ft elevation. Overlap is 57°.
