You can check Hughes, they sell EGGE pistons. They are CAST ROCKS! maybe 9:1 compression and $$$ I Think Ross has some customs that will work at 9.5:1 or so but even MORE $$$... FWIW... part out the 413 and build a 440 block with the parts! That's what I'm doing. Salvage the crank, caps, rods, ECT... put them in a 440 NET GAIN: more cubic inches, cheaper pistons... the machine work cost the same for either why waste your time? If you're hung up on a 413 for a specific build? Slap some decals on it that say "413" who will know

VERY true ... the 440 does not have that issue .. but look at the 413 and 426 Max Wedge ....
It used a larger intake and exhaust valve than most 440's used .... and even larger than what the aftermarket offers.

Not a thing wrong with the 413/426... just from a pure economic standpoint, it's just not practical to build it for me, and it seems others have tried it too. I picked up Ross 9.7:1 pistons on sale at Jegs for $450 delivered for the 440... Hughes wants $520 plus freight for the low comp/cast 426's. I got a deal on the bare 440 block...My decision was easy  The 413 gets bolted to a cart and moved under the bench. Still wonder if the 413+.070 with a 4.15" arm, and custom 383 pistons is practical as a 472" stroker  Someday maybe I'll try it

as Andy said, if they make a 383, just move the pin!
