I also have trick flow track heat heads on my 94 302 motor. The motor has a 750 DP carb. I love the heads and wouldn't buy anything else but that's not fair to say since I haven't tried the others. I do know that when I did my research on the heads they where the best choice and I got the heads complete for $1,000 and that included shipping. I have a ton of room for valve clearence with a X303 cam. I did alot of searching on the 5.0 sites.
