THRU MY CALCULATIONS, I FIGURED YOU HAD A GASKET BORE OF 4.100", and a -.010 deck height, and getting the chamber down to 61cc would get you actally 14:1. which would mean .006 usually per cc, so 64-61=3 and 3ccX.006=.018. .018-.020 should get you there. tell me your gasket bore size and deck height(how farpiston protrudes out of deck) and i will give you a more exact figure.
