Ok I just searched around for a compresion calculator and I came up with about 9.5 to 1 with the 67cc head and a .039 compressed gasket so I will most likely order the 67cc torquers.
Still need help with a good cam, intake, carb though??? Also what size stall should I use for which ever cam is decided on. I'm really leaning towards comp cams magnum 286h with 286 duration and .490 lift on a 110 lsa if that would be a good decision for the combo
