Johny you can use the 76's (RH) on the LH,so you basicly have 2 sets.
If anybody has the old design 77's (LH) they too can be used for RH will need to drill a hole on the protruding part of the gasket for oil passage.

I even had the idea if we were stuck with LH gaskets we could groove the head or block for O-ring just like the early oil pick up.

I don't like publishing info until a project is 100% complete, but in the case of head gaskets and the concern for future availability, I'm going to go ahead & fill you in on the status.

I have placed the order for the tooling.

Gaskets will be made in the same LH & RH configuration as the OEM gaskets

Gasket material will be graphite exterior with a steel core sandwiched in the center. The design & material is virtually identical to the current offerings by Victor & FelPro for premium head gaskets.

Before any gaskets are offered for sale, they will be tested for 2 days continual running on an engine dyno, making 50+ power pulls, and thermal cycling from high operating to ambient temp.

Availability? as soon as possible, 4~6 mo estimate. None will be produced in quantity until engine testing is completed.

The OEM material, Astadur, is now old technology, it's expensive and virtually unavailable. Event if it was readily available, the tooling cost would be exhorbitant as specialized tooling is required to make the cuts smooth.

The compressed thickness will be abt 0.005" thinner than the OEM. I've measured the fire ring height on over 80 cylinder sleeves. The variance is very tight, 0.041", +- 0.0005". Net fire ring clearance below the head with the OEM gasket is very close to 0.020", ample room for clearance with the new gasket. If anything, the new gasket and the associated reduction in fire ring/cyl head clearance could result in a cleaner burn. Another very slight change would be a minimal increase in compression. None of these changes are expected to have any noticable effect.

There you have it.

D, no problem using two RH gaskets. If you don't find a left, buy another right.
