Curious. What compressed thicknesses is this gasket available in?

[Robert C.]

Zero. It is a dry deck. You will have to have your pistons in the hole. There is nothing between the deck and head.

Marty can explain it better.

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?

[Robert C.]

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.

They look like they are made from Monel.

Pretty Neat.

[wheneaglesfly]

Monel 400.

This may change the Twin Turbo world very soon

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.

[cgeise]

what about the rings working on the aluminum head causing the head develop wear marks ?? Similar to the old head gaskets with steel o ring in them.

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.

Yes you will get some of that.
We found if you put the heads back in the same place it was not an issue.

[cgeise]

My concern is for guys that put a lot of hits on every year will the wear issue turn into the same issue as head gaskets -- meaning the heads need to come off every 30 to 50 pass's for replacement/ decking ect ???

It depends on how many times you take the heads off.
I went 150 passes and had no issues. Than ran a different combo on the same rings.

The reason I did the rings was we got tired of changing head gaskets.

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.)

[60man]

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.

[Tom Vaught]

Wonder if any of you ever heard the name "Big Bill Edwards"?

He was running a 301 Chevy in a Ford Ranchero at Bonneville and and was making 1200 HP with the engine at 60 psi of boost pressure.

I bring this up because of Bruce Wilkie's post #35. Bruce suggests that you could use Rubber O-rings around the coolant holes between the block and the heads.

That is EXACTLY what "Big Bill Edwards" did on his little chevy engine. He also ran a sealing ring in the block that sealed to the cylinder head. Bill's ring was gas filled.
Don Vesco knew Bill personally and had bought a set of gas rings from Bill at one point.

So as I posted previously, Vesco had the first gas rings for Marty's deal made for Marty and I.
The rings worked well in "Big Bill Edwards" 4 HP per CID engine if he did not go crazy with the boost (which Bill always did).
Marty's ring design sealed up the 406 cid Pontiac engine for the 3 years it was raced and it also was making about 1600 HP.

So the Sealing Rings do work, the rubber or Viton O-rings do work.

Have fun out there.

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

[Tom Vaught]

The gas rings at work change from a round shape to an oval shape.

That means that the ring gets wider so you need a groove that allows the ring to go oval without touching the walls of the groove the ring is placed in.

The ring will compress about .015" downward without damage so the width of the groove has to be designed to allow that movement.
That also means that the ring can follow the head and still seal even with .015' vertical stretch of the head bolts around the cylinder.

Marty's ring is a different design. It still follows the head somewhat but I have not discussed with Marty how much movement of the head the solid ring will allow and still seal up. Marty could answer that question for you based on his testing.

So to answer your part of your question, the gas rings would stick up above the block deck .015" (The rings are .090" in ring tube diameter.)

With no barrier between the aluminum and iron, have you seen any itching between the 2 surfaces with material transfer? Any micro-welding?
