Okay, I have a 1998 Mustang GT Convertible with the 4.6L V8. I don't know anything hardly about engines but I'm looking for the BEST cylinder head and new cams combination that I can get for around $1200 or so for the heads and don't care much about price for the cams. Anything you all can tell me will help and I don't mind spending more money depending on the horsepower difference. Like I said before I don't know much about engines so if you could reply "get this and that, here's the model number and how much horsepower gain you should get out of it" then it'll REALLY help. I'd also like to know what to look for in buying them and what all else I'll need to have them installed. Does the engine have to come out to install them or not? Anyways I'll cut it short here and kick back and wait for the replies, thanks so much in advance!
