I know we went over this before, but here is my question again. With the speed pro hyper piston h345acp30, which are -6.88cc and a 1.548 compression height. If I put this info. into the calculator on eaglerod.com with 64cc heads, 9.025 deck height, rods 5.7, stroke 3.48. bore 4.030 and .041 quench. I get around 9 to 4 CR. First question is in reality my quench will not be .041 since my piston are 1.548 not 1.560. What will be my quench then? Also if I use 58cc heads then will I have a better compression than using 64cc?
