I have the 295cc'd set with the upgraded spring to accomodate a .650 lift. They are a double spring with a Dampner. Also, what kind of seat pressure and open pressure i should see with these springs? I have a solid roller .621 lift. Thanks, Steve

Thanks, Steve I don't what brand of springs that Indy uses but I would want 250 lbs pressure minimum on the seats and 550+ open. When it comes to valve spring pressures on race roller cams, more is way better than to little Not every solid roller cam has the same lobes so the more radical the lobe the more spring pressures are needed to keep the lifter on the lobe all the time, you don't want the roller to lift off of the lobe or slide down the back side of the ramp Mr.Cab Racing and winning with Mopars since 1964.

Unless you specified a solid roller when you ordered the heads then it would probabl;y came with the spring listed above.
