If that's the engine from his INDY car he told us he used gas filled "O" rings,
thanks harry. the two o-rings per cylinder are concentric; the diameter of the o-ring circle is 4.1" on the block, and 4.2" on the head. double ringed.
So with Right Stuff etc to seal coolant and oil, o-rings should be good for the long haul?
the rings i have are steel (or stainless). hmm, i just pulled out the box, and i may not have a complete set. looks like what i have is tail-ends of sets of 8. the marked bags are from JABCO. some are large wire ID (.040 by eye), some have rectangular cross section, some are packed round+rectangular, and one is an odd crushable? ring, shaped like a tire ("U" cross section) with another "U" ring inside it.
i have other exotics, solid lifter/adjustable pushrods (stock, hydraulic), cast timing cover for camshaft driven fuel pump, cast stainless turbo manifold. likely won't use that stuff.
