ok people finally got finished doing my 351w swap in my 92 coupe.my question is i did a compression test on all 8 cylinders and came up with about 110 psi on all. the heads are edelbrock performer rpm with 202-160 valves and i think 60cc combustion chamber.im thinking i should try and get these heads milled down some to help pick up some cylinder pressure.any thoughts does this seem low for cylinder pressure.....
