JAM Valvetrain

[alex]

I just bought a head with JAM springs, retainers, and valves along with 1g cams for my 2g setup. I was able to get an outstanding deal on the whole setup for $250 with everything already put in the head along with 1g cams which will save me alot of time.

My question is if anyone out there has used these types of springs and how they performed out on the road/track. What were you able to rev up and how well they lasted. I'm eager to hear different responses and the outcome/result of the JAM valvetrain.

Thanks,
Alex Smedegard

Sorry to bump this, but I know there are people running this kind of valvetrain out there.
