Well i'm getting Thumper ported heads and his website says springs for 500 lift and i was just reading around and people with 1.7 rockers and cam is too much lift for the springs. is that true or what? another question before i start buying stuff is once i get my ported heads from thumper and TFS 1 cam what roller rockers should i get? 1.6? or 1.7? and should the springs in Thumper's heads be ok with the cam and rockers?
Ported heads, 1.6 or 1.7 rockers, and TFS 1 cam = too much lift for the springs?

You can get upgraded springs with Thumper heads. Im considering this myself. Anybody else?
Off Topic: I know this dosent matter but how does the TFS 1 cam sound is it choppy?
