I'm looking at different pistons for a build and was looking for a stocking piston that has plenty of valve relief otherwise I'm looking at custom pistons which the guy I'm building for gave me a budget and I have a fairly short time frame.

Well it says good to .650 lift cam and they usually give the safe quote on that.

what lift cam, heads and how much off heads?

Going from memory (but I, too, suggest calling Ross for the specs):
Int - .220"
Exh - .200"

You should probably ask them what the cutter diameters are, too, in case you're running valves much bigger than the common 2.19" / 1.81" for some reason.
