I've got TFS TW aluminum heads on my Stang with no problems whatsoever. And I picked up the most HP and TQ than any other mod I've ever done. (Even with the 2.02/1.60 valves and 65 cc cambers!)
Thousands of people have aluminum heads without any problems at all.
Bennett, Keith Craft, Coast, DSS, etc., all use aluminum heads on their race motors. In fact, Bennett just released a new head for SB Fords that is all ALUMINUM.
Go with a nice set of TFS, AFR, Edelbrock's or whatever and you will be happy.
