depending on the piston pin location in the particular flat top pistons (how far in the hole at TDC with the Vette rods) and the amount of lift on the "monster" cam and the reliefs depth in the pistons and the rocker ratio,,,

he wants to confim the valves are not hitting the pistons ...

he gave you just one example of many items to be measured and checked....
(likely/possibly based on your choice of wording to describe the problem sound????)

if it is indeed a "monster" cam duration, (2500+rpms operating range, 8-10Hg idle at 1,000+,,,etc) you do need better heads/higher stall convertor/lower rear gears/probably a MSD box/headers/different intake/etc= alot more $,$$$'s!!!
now is the time to decide if a more street friendly grind duration and lift cam is "maybe" a better choice....
