alternative to Comp springs?

Are you checking them with the retainer?

Did you run them all down to coil bind 2 or 3 times before testing them?

Can you not balance the seat pressures with shims(and still have ample clearance from coil bind)?

If none of that works for you.... a PAC 1908 would work, but you’ll have to lose some installed height(-.050 locks) for 115 on the seat.

Yes I checked them with the recommended Comp retainer. No I didn't compress to coil bind 2 or 3 times. I wish I had thought to do that as I don't have access to the Rimac anymore. It is owned by a Top alcohol racer in a machine shop. And the same goes if I wanted to use the shims, I would need it for a quite a few hours to do every spring several times and log it separately etc. Re, that PAC spring, it looks to be a little lighter than the comp but probably a better quality. But I am also wondering how many valve spring manufacturers are there? Would every company make their own springs...? I doubt it, they most likely outsource production to spring manufacturers with contracts based according to their own requirements and specs. That 1908 PAC is a perfect Mopar size but is a little light unfortunately and also don't think it would handle the 0.525" lift, looking at the heights given on Summit... even if I didn't eat into some of the installed height to get more pressure.
