compression ratio on a 305

i already know that the 305 LB9 engines have 9.5:1. i just bought L98 vetter heads... i want more compression ratio.. the engine as bored .040 and i have to use the 350 head gasket what can i do to get more compression besides milling the heads or new pistions

------------------
305, TPI,compucam 2030 cam, air foil, 8.8 wires, accel super coil, dynomax headers, custom y-pipe, cut out, 80 series flowmaster, 2.73's and an open diff(3.42-3.73 on the way). and a stage 4 chip :0). hittin a sad 15.2 before the chip.

Nothing

Those are the only two ways

unless you run super rich and get excessive carbon buildup
