I and building a 383 stroker. The block is been 0 decked. The heads have been milled 2 times EVER and no more than 15 off each time. I am planning on running a MONSTER cam and want to make sure I will be ok. I had the motor all together once with a cc306 in it and had no problems. (felpro gaskets) The intake had NO problems fitting either. The cam I am running is a Comp cams solid roller 266int and 276exh dur @50 and .640int .649 lift with 1.6rr. the cam is ground on 108 centerline and has a 112lobe seperation. Should I have problem with the pistions hitting valves? I plan on running a STOCK head gasket .47 thick.

Thanks
Matt
