Aluminum heads whos the best?

How much power you looking to make? What parts you got so far?
Power: is unknown at this point (I really should know but haven't put much thought into it).
Parts:
Stock stoke, Stock rod length, bored .030 over. Hyd Roller Lifter, Roller Cam, Roller rockers. Was going to use stock x-heads (with stainless steel Ferrea Valves), with a 9.7 to 1 Compression ratio. With the aluminum heads, going bump compression (at least try to) to ~11.1 (93 octane all the time doesn't bother me). with Dougs headers and Air gap manifold.
