wayfast the heads were on an old 355 in a 3,400# car and was going high 10's low low 11's,but that was with 11.0-1 cr ratio and a massive cam.

for u i figure it best to keep the cr to 9.0-9.5-1 and a cam around 224/234@50 .520/.510.to let this thing have nice street manners and to keep the power level down.u by no means need forged pistions,alls u have to get are hyperetic,

from summit for a whole engine kit flattop or dome pistions/w rings , bearings,oil pump,freeze plugs,full engine gasket set is ;about 300,if the cam dosent go any larger then what i posted above the springs on the heads are fine,and ur looking at 100$'s for a cam.
what were the specs on the cam u have now?
