Thread: Valve spring question

Hi, im installing a xp hot cam with everything zzp reccomends the issue is they are out of stock of the 136# springs althrough jegs may have the ones i think zzp sells -

COMP Cams CONICAL VALVESPRINGS .650/.920D 438LB R Part Number: 249-7228-12 Rate: 438 lbs
Inner Diameter: .650'' Top, .920'' Bottom
Outer Diameter: 1.020'' Top, 1.290'' Bottom
Seat Load: 136 lbs at 1.800''
Open Load: 412 lbs at 1.170''
Coil Bind Height: 1.125''
12/pkg


The thing that is throwing me off is i thought the zzp 136's were beehive springs and Jegs are conical springs also im not sure if the Jegs springs are meant for an LS if so i would thing they would work for sure.

I would go for these instead. I'm not a fan of comp springs. Too many people have lost engines due to them.
