I think the reason that your pistons are overextending into the barrels is
that you have the wrong crankshaft. Check out Harry Fenton's excellent web
site on Continentals.

He explains all the ins and outs of modifying Continentals. At our field we
had a Continental with a mix of parts, C-85, C-90, O-200 and that baby made
around 130hp! Never saw a Luscombe perform so well !
