valve springs im looking at doing a set of dual valve springs to go along with my cam. the cam is going to have long duration and is going to be over .600 lift. im looking at the comp 921 springs, but some recommed that i use the patriot ones because they are a lot cheaper. i just want some opinions on these and to see if someone has had some bad experiences with them.

On a cam with only .600 lift get the patriots. The 921s have more open pressure (400)and less seat pressure but the patriots are much cheaper and have more then enough open pressure for that cam (350-360pounds, 140 on the seat).
