Do you think I could run 13.0:1 J&E pistons on pump gas?

I think custom is the way to go too. Got quoted 50-60 bucks per valve which isn't too bad. I'm going to leave it for now but and see how I go.

I found a set of aftermarket oversized valves for the 250 on a japanese website once before. I can't find it now.

Thanks in advance.
