Lars, are you aware that there are two different styles of
Oldsmobile heads? If you're stroking, you probably want
the 51 cc heads or, better yet, the 54 cc Buick 300 heads.

Thanks, I think I'd like to investigate the use of aluminum Old's heads
assuming I can get them in rebuildable shape. I won't mind modifying
them to use more modern valvetrain assemblies if need be, since I expect
I'll have to ultimately build custom heads anyway. And I want to keep
the cylinder bore stock for now (but stroke the engine as much as possible)
to get as much power at low RPM as possible to direct-drive the propeller
instead of using a propeller speed reduction unit, which adds more weight.
