1983 Mercury Capri carbed 306 trickflow valve springs

I got some TFS valve springs iam installing on my car, and i wanted to know how much of a diff will i see in the high rpms? I have a E303 with the stock springs and heads and it always felt like it was floating the valves at about 4800-5000 rpms.

Those springs should help stop that valve float. They have enough pressure to support up to .540 lift so they should be up to that E303.
