Either new pistons, or add new intake valve reliefs to the current pistons, which can be done without taking apart the short block.

If it were you would you bypass the p51's and go straight to a A head with new pistons of course.

Well, that would depend on what I was trying to achieve.

So, how much material would one be removing from the top of the piston if this can be done "in block"? Are you talking about welding a cutting tool to the head of a valve and bolting the head to the block, then cutting the relief as such?

There's no reason to make your own, you can buy them from several sources. Fits in place of the valve and attaches to a drill. Pocket depth would depend on the cam being used.
