Who makes a dual pattern piston?

Who can make pistons with valve reliefs for standard (stock / Edelbrock), and A460 style heads?? This is so I can get a motor together using Edelbrock heads at first, then just be able to swap on an A460 top end at a later date.

Any custom piston manufacture will make them for you, just be aware that you will see a large compression drop when going to the A460’s with a flat top. And I wouldn’t try doing it with a dome.

Unless it is a big combustion chamber Edelbrock or D3 style combustion chamber head, originally.

Thanks guys. The Edelbrocks are 73cc
