See sig. How much lift can the valvesprings take on these heads? I am about to change my current heads cam setup and want to do the cam first. I bought my heads very soon after they came out. I think patriot has switched up the springs once of twice by now......I know they have Ferra valves and some sort of comp springs....just dont know which ones.

if you have the older none gold springs im sure PP would send you a set of the gold springs since some of the older ones had isssues. they've also upgraded to viton valve stem seals over the older telfon ones.

Definately check on the color of the springs. We have the double gold springs in stock incase you need a set of them They are definately alot better than the previous springs that alot of guys broke.
