The Eagle 4340 crank is an awsome choice! Port the heads while the engin is apart, you will thank your self later and even save $$$ in the long run!

One thing you should consider is to O ring the deck if you are going to run that kind of boost. IT will help prevent blowing head gaskets. Yet a proper tune, you should not have a problem with the head gaskets. But that's waht we pay for in our hobby, extra $$$ for prevention, forged crank/rods/4 bolt main's......

Spend the extra $ and get the heads ported, the deck O ringed.
