440 Stealth Heads with Comp Cam Springs?

moper said
The comp 925s are stiffer than the Stealth factory springs... but if you're at .578 you could be having coil bind issues. I'm more inclined to think the 1.6 rockers might be hurting it more than lighter springs. What's the issue? Noise? lack of power?

It sounds like 16 collasped lifters....do you know the specs of the Stealth springs.....the 925-16 are what are specified on my cam card....

COMP Cams 925-16 - COMP Cams Valve Springs Valve Springs, Dual, 1.510 in. Outside Diameter, 395 lbs./in. Rate, 1.100 in. Coil Bind Height, Set of 16

I know my buddy Paul is running the same 1.6 ratio rockers on eddy heads with comps springs and their roller lifters with no problem......engine builder at machine shop mentioned that also....the problem is I do not know the coil bind height of the 440 Source ones.....

Number one intake valve full open.......
