3k or 4k gsk kit w/ only basic mods?

With my old silver bullet on the truck I would push 50psi @ 3000 rpm with stock springs ( 180k miles on them) and never had a valve float.

Go with the 4k springs, they fuel alot harder in the lower rpm's and if you plan on doing more mods in the future you wont have to worry about the gov springs. I havent put the valve springs in mine yet either and I have the 4k gov. springs. Wouldnt advise pulling past 3000-3200rpms without the valve springs but you dont really need to rev past there anyways.
