Will this clear?

Max lift occures when the piston is all the way down in the cylinder bore. Duration is more of a telling statistic of p to v clearance then max lift is. I would say if you stay under 230 degrees duration @ .050 you will be ok. But don't just take my word for it... Clay it! I did with my AFR's, and big ol' Comp Cams cam with those pistons, and it was real real close... but it worked.... I think I was a little closer then what people recommend for a "street" application, but it worked.
