ERA Chas hit the nail on the head,
especially the better heads suggestion on your stroked engine.
I tossed my iron heads years ago.
I have an itty-bitty 427FE with KC Stage II heads, and 2.25" valves. My cam is a roller with specs a little larger than those you mentioned.
I've been running a pair of tweaked Holley 600's for years, and this engine is strong and driveable. I'm waiting for a pair of tweaked 750's from one of the engine builders on this site (he suggested the 750's based on my engine's characteristics).
