Valve Spring?

[wrench1]

What is the best flat tappet valve spring to use for durability in higher rpm application?

Come on, you need to give out a little info, like duration, lift, lobe profile (how aggressive), steel or Ti retainer & valves, etc...Your question is kind of like what is the best engine for my car??? LOL

if you looking for just brand names pac or psi would be the best springs.

psi pac manley all i use. a used set of psi's are usually better than comp crap or less expensive ones.just check pressures

The 26 hundred prefix part #'s from Comp, are PAC, the cheaper ones no telling (prob the cheapest bidder).TB
