Any thoughts on this 340 combo

I have a .030 over 340 im building. TRW forged pistons, scat rods, factory forged crank, assy was balanced. ill be running a comp XS282S .520/.540 lift 244/252 duration @ .050 cam. HS 1.5 roller rockers. Holley strip dominator intake, Undecided on the heads. I have a fresh set of ported X heads that flow 270 @ .550. Comppression with the Xs would be 10.5:1. Thinking about buying some eddys that would bump the compression to 10.7:1. w a .040 head gasket, or little higher w the .025. But without port work will flow worse. Dont believe i need high flow #s with the cam i am running, small cubic inch engine, and will only be turning 6500. It is pretty much going to be a street engine. Want it to run fine on 93 octane. Am also considering an PRM air gap. Anyone running a 340 close to this combo? Going in a 4 speed w 3:91s
