It seems to require a special head gasket, maybe for bigger valves. Does anyone know of a source for these gaskets?
As always, thanks!

I used one for 35 years on a stock 1917 motor. I used a stock copper gasket from Langs or Snyders. That head made a big difference on a 1917 couplet.... a heavy T.

Re: Rod Jensen Aluminum 6:1 head
I did a run of special head gaskets a few years ago for big valve T engines. It actually started with head gaskets for F head engines and then expanded a bit.
I still have the digital drawings so could make another one. They are solid copper and work OK if used with “ Hylomar” as a sealant

Re: Rod Jensen Aluminum 6:1 head
AFAIK they worked with a stock gasket. Any indication that the head has been modified around the valve area? If so, you can modify a copper sandwich gasket by opening up the flanged sheet gently, removing the filler material and then forming the flange back with a tiny hammer. This is much easier on older gaskets where the interior is asbestos or beater board. In the newer gaskets, the filler layer has a layer of steel in it that must be removed and this requires detailed attention to cut it out of there. I've found the tiny abrasive discs in a Dremel tool work pretty good for this, but it is tedious work.
