I thought of that but run into valve clearance issues. JE doesnt have an off the shelf option.
I use Wiseco forged pistons modeled after the domed stock pistons.
Cutting eyebrows into pistons isn't that difficult. The hardest part is locating them properly.
For that I mock up the engine with no valves in the heads. Then with each piston at the top of it's stroke I use a transfer punch to mark both valve center positions on each piston.
After that, mount the pistons at the valve angle on a milling machine and use an appropriate diameter end mill to cut the pockets. Each piston requires a unique pocket pattern, unless you cheat and use a large single pocket for both valves. For that you just traverse an end mill large enough for the intake valve across the piston. Using an off the shelf piston that has a single valve pocket as an example can eliminate the effort of mocking up and marking each piston at some expense of compression ratio.
It is valuable to understand that the closest approach between valve and piston does not occur at TDC. Pocket depth should allow at least .080" clearance at the closest approach.
