Why not just find some valves that work with the valve train parts you already have? A good machine shop should be able to recommend some valves that will work like Isky, Comp Cams, PAC, etc.

I don't know? It's all Greek to me!
I just want to eliminate valve float at higher rpms with the spring kit.
The tech person at American Muscle said that I would need those additional parts.
They don't stock them.

You need to contact Ed Curtis @ FTI. He will know exactly what you need.

Do you have valve float? Really going to depend on your cam specs that you are using.

I second talking to Ed. I got my cam and spring kit from him, as he sells complete kits.

I would say yes for valve float. Not all the time. But I can tell sometimes when it lays over before the stripe with certain weather conditions.
The motor is the old Ford Racing Crate stock 5.0 bottom end with the B-303 cam and the Gt-40 X-303 heads
I've read that the Gt40 x-303 heads are only good for like 5500-5800 rpm I guess. I am hitting the finish line at 6000-6100 rpm.
I want to buy heads that will flow 6000 rpm and a new cam but, It's not in the budget right now.
Thanks for the link! I will give him a call.
