what are the best heads for a 5.0? i heard the M-6049-X305 gt-40 heads are bolt on 65 hp. and they have 58cc chambers wich would make it 9:4:1 compression wich is what i was looking for. has anyone tried these heads? what are they like? what is the power band?
If these are going to be used in a truck, I'd stay away from anything that has an intake valve size larger then 1.94, or an intake port larger then 180cc. What everyone has suggested so far, should work well for you. Muscle Mustangs and Fast Fords magazine had a real good article in one of their issues, where they compared several 5.0 cylinder heads. (dyno tests and flow tests) They may have it on their website.
thanks for the info guys. i will be buying most of my parts from mopac and i dont think they handle AFR heads are they similer to the gt-40s or should i buy some brodix st50 heads and get them milled to 57cc chambers?
