It doesnt become and issue until you are over 5 degrees, but let me tell you, you run out of piston to valve clearance before the engine stops responding. Custom pistons with deeper valve relifes are needed with these motors badly.JDM_2ner said:I am wondering the boundaries of valve clearance in relation to running SR16 pistons (12:1 in a DE) w/ C3 cams and cam gears. I know that with the cams at 0* there will be no piston/valve clearance probs, but what about when advancing/retarding as much as 2.5*?
