compare the 8:1 and 9:1 and 9.7ish solutions with what AJ posted
I'd start with the 9.68 solution pistons and late heads and open the chambers a little if that too much compression (as opposed to using thick gasket keeping the quench)
the cam Bullet recommended was for sealed power NOS pistons most likely stock or lower than stock compression
YMMV
I asked the poster in that thread for the compression height so we could compare EGGE, domed, and other piston solutions- you might PM him
IMHO most of the book cc's are smaller than reality
CC yours and see which posters have cc's theirs- makes a big difference especially on a small motor
which is much easier to over duration cam than say a 360 or 400
