Trick Flow heads are roughly $2000 and are fully ported right out of the box. Best deal going that I know of. Only potential issue is valve cover clearance since they are taller and spark plug clearance due to angle plugs.

Edelbrock heads are a good choice but unported heads are less power and ported heads will cost more than Trick Flow. Ported Stealth heads might close in price to Trick Flow heads? Not sure about how performance compares.
