I'm doing a couple builds using Jay's new heads. Jay provided me with the solid models and data so that I could get that information to Diamond. They knocked out a full custom set of pistons for me in about 3 weeks. Since they have the data now and have made pistons to suit, they can provide pistons for those cylinder heads at anytime.
These are for a 511ci build, 4.375" x 4.250". Moly coated skirts, vertical gas ports, setup for Molnar Power Adder rods and a .8mm ring pack. I also had them provide a set of Trend tool steel H13 wrist pins since we will be pulling vacuum on the crankcase.
Nice pieces.

Cool!
I ordered pistons through Jay's contact CP. They could arrive in another week or so. Will post up a thread just as an FYI.

Got mine through CP as well.
Curious Brent, what’s the CR on that motor? I was hoping to get a piston that looked exactly like that with a deep enough dish to get the CR where I wanted it ( still second guessing my CR….)
needed a bigger dish, so my pistons have very little in the way of quench pads .

You really don't need a lot of quench pad. We've proven over the years that a full spherical dish (like a bowl) works really well.

Brent, are the pistons set up so that they will work with stock FE head valve locations as well as the valve locations in my heads? I thought that was important, all the CP pistons that I've specified have that feature...

I didn't request that, so not sure.
