When I put my engine together I did not check the valve to piston clearance. I have stock Vortec heads with a ComCams XE 268, flat top pistons, and stock stamped 1.5 rockers. My block was never decked. I am wondering when I get roller rockers if I have enough clearance (valve spring coils and piston to valve) for 1.6's or 1.52's. So, who is running the highest lift or is this pretty close to the max.

------------------
350 Vortec, forged flat-tops, CompCams XE268, Edlebrock RPM, Holley 3310, TH350 w/Holeshot 2400, 3.23 posi, Heddman shorties, HEI

 

SDPC says the springs will tolerate .450" of lift.
