With Pro 2's and 3's. valve to valve is pretty tight with stock valves. With OS valves, you are going to have to start dialing out overlap. With most aftermarket pistons, piston to valve is not as big an issue.

well they are arias pistons. 13.5:1 w/7cc dome. this is the first time ive used anything o/s in a setup so i dont know what to expect yet for clearance. but i will find out i guess when i degree everything in.
wont be for a while tho. im saving up for FJO ems. which is about 2000$ for N/A....
