Default HELP-Closed chambered heads and using Open chambrd pistons

Got a set of closed chambered BBC rect 291's that have been opened up (measure at 109CC) and I've got a new set of Speed Pro (TRW) L2308AF30's that I would like to use. It's a pro-street car so I would like to try to stay below 12 to 1 CR. Does anyone know where to cut and/or how to take some of the dome off ??

you need a "mill" and wiegh each one for balance, i took mine to
a machine shop and they did a good job, w/closed chamber heads,
flat tops work well, are you going to run racing fuel on the street
if you run 12: to 1, does your cam match the compression?
:wink: good luck
