your cr of 7.24 is not much at all for an engine. but put 10-15 pound of boost in there and your going to probibly have gasket problems. on my 270 i ran a small port 270 head that cced out at 104 with gasket.i ran about 8 pounds and i did lose 1 head gasket. i'm now runing a 302 head with valve work and i'm not sure about ccs on it. but i upped the blower speed to 15 pounds. one thing about the gaskets is i think you need to retork the head maybe 2 times. my cam is fairly mild at.442lift,270 duration and 112 lobe sep.if your cam is an isky mine has isky and the grind no. on the back end of the cam. my ride is a 53 2dr. with a 471 and a 700r4 with a 9in and 370 gears and 25 in tires. its just a cruzer but it has really shocked several large v-8s for a big old 6 banger it really gets it on!
