Default AFR head / piston valve relief question

Has anyone put a set of AFR210's on with stock pistons? I have a customer asking about this & have no idea if the piston valve reliefs are large enough to clear the large dia valves.

I even asked AFR & they said, "never heard of anyone trying that large of a head w/ a stock piston".

Any ideas?

Thanks in advance.

I wouldn't think so. I have a set of LE3's with 2.05/1.60 valves. I am going with a 383, but I asked just for the heck of it about the stock bottom end, and Lloyd said there is no way the stock pistons would clear those valves with my heads.
