Open spring pressure is 274. The cam is the Lunati 10200701LK, .454/.475 lift, 213/220 duration. The springs are the Lunati 73262 with 346 spring rate and 274 open pressure @ .454.
So, the Lunati springs I have installed are the springs the manufacturer recommends. I'm not understanding something here.
Yeah, I do feel foolish for tossing the springs that came with the heads, but I really didn't think I'd have a use for them. I ended up selling the 901s on eBay, also for the same reason.
The rotators actually came on the 302 heads, and I swapped them out for some standards from the old heads.
Once again, I'm very grateful for all the help. Anytime I feel like I have a stupid question or screw something up, nobody has ever been condescending and always jumps in to help when they can. That certainly fosters a learning/teaching environment. This is a great forum.
