I was just adding up my cam kit on thunderracing.com and noticed they have Isky springs that are good up to .550 lift and are only single coil (so then I wont need machine work done to my heads)

Are these Isky springs any good? I'll be using 230/236 cam, chromemoly pushrods, 1.6 rr's, etc....

 

Id look into the EX 612 valve spring kit that combination motorsports offers. They are $109 for springs, lightweight chromoly retainers, and locks. The springs are rated to .600" lift.

 

almost seems too good to be true

 

How about some beehives? I'm giving these a shot for my heads & cam swap. A little pricier, but from all the research I've done, they look to be the real deal so far - especially with folks like Ray Bohacz giving them the thumbs up.

 

I'll probably go with the:

CRN-10308-1 Crane Aluminum LT1 Head Valve Spring Kit
fits stock head without machining, good to .600" lift, includes retainers, seats, and locks

For $179

Its worth a little extra money for the name brand I think....

 

I'm looking at beehives, but findong a proper spring seat for the LT1 is ???
Jkipp84: are you using the L98 spring seat?
