just cc,d my heads will this be too much comp. ?

Running some numbers, you'll end up around 9.7 SCR with a standard Felpro 8553 PT head gasket, and around 10.0 with the Felpro 1008 head gaskets. With the TC stall you are listing, it sounds like you will have a pretty large cam, so should be OK; just take the normal precautions in tuning up.
