Re: Comp 921 Dual Springs @ www.ls1speed.com
What are the pressures of these springs? Would I need different shims/seals to work with my heads?

Re: Comp 921 Dual Springs @ www.ls1speed.com damn, that's pretty high for a set of springs. i'll wait and see how they turn out before i fork out that kind of $$$ for a comp spring.
