Thanks for making these, the boost guys will love the fact that lifting the heads a little won't be a new set of gaskets.
How far in the hole will the piston need to be?
Will there be other sizes or will this size work for a smaller bore?

Depends on rod type. Most steel rods use a .040 gasket. So .040 in the hole.

Aluminum Rods need more clearance from the head to piston top.

When ordering a IA II block with a 10.300 deck height there is no change in the distance of the wrist pin to the piston top. And if you need to cut the deck to 10.230 Stock height there is still no change when using a .040 gasket.

So it is a good sealing system for a dry deck motor.

The heads lift under boost so the rings needs to float somewhat.
That is key to how they function. ( more pressure more seal)
You can plumb a water block for street cooling if needed, although it was made for a race only application.

Marty, did your factory block have water in it or did the alcohol do the cooling?
Wondering if I could plug all the holes in a factory block and even the E-heads and do some reverse cooling.

On my block we used both water and alcohol. ( we found the water was not necessary)

Yes we did that on Scott Schraders street car.

Just a thought, but IMO you could likely stay wet deck IF you countersink the block/head water holes slightly and use either rubber o rings or Right Stuff.
Water isnt very likely to get past Martys rings if you managed a water leak, and water pressure is unlikely to get high enough to blow out o-rings or Right Stuff. (I havent used water neck gaskets in years, just RTV. No issues.)

I had the "Tiger Mod" done on my Tigers.
But I'm not boosted but run 14.8 CR.
Seems to be working.
Maybe next combo.

Thanks Bruce and Tom seems like a good idea, how far do the sealing rings stick up above the deck?
