Yeah, this stuff is a bit over my head. I'll RTFM as best I can, I
have to search out a place for good automotive tech books.

My working assumption is that all these parts (head, block, crank,
manifold) go together, but I don't REALLY know that. It seems
certain that Navarro did only one engine, but there could ahve
been more blocks/heads, trial parts, etc that A won't fit B.  It's
almost more likely I have odd/junk parts than an 'indy engine
kit'. The unused junk stays on the shelf, the good stuff goes into
the project, gets broken, given to friends, sold etc. Gary did say
that it was engine #1 that failed, disassembled for inspection,
and shelved, but it sat for 30 years...

So for all I know the double O-ring business are mismatched parts.

THere's a whole story to be told in the head gasket area. One of
the RAMBLER headgasket boxes has a roughly hand-cut incomplete
gasket made out of some beige material. There's a lot of gasket
goop in the head (sealer and O-rings only? no gasket?) There's a
lot of gaskets here, and no documentation.
