Ok, Valve spring/pushrod/lifter question... Ok, here are my plans. I am going to install my new CC 212/218 .522/.529 @ 114 cam here in the near future. Also I will be exchanging my heads with some home ported heads, and I will not be raising my rev limiter. My questions are:
Will LS6 springs be suffieceint enough with the smaller cam, or should I go with a CC spring or Isky?
Will the pushrods need to be replaced?
Will the lifters need to be replaced?

Re: Ok, Valve spring/pushrod/lifter question... Not sure why are you going to such a mellow cam..?? My b1 is very streetable..slight lope..you barely know its there when you rev it..no surging problems.nothing and great sotp gain with just my current mods and ls6 intake.
I did put in better 918 springs and moly rods and even went to titanium retainers but they aren't required.My car ran ok with just the tb hole drilled 13/64 and I reversed my tb idle screw and tweaked it up just litte bit..about 100rpm.The cam screams from 3000 up.I personally wouldn't go much mellower.its also 114 lsa and 221/221/558/558
and its supposedly will pass emissions.For the cam you mentioned I would probably go with the slightly mellower 915 springs and moly pushrods,they use stock retainers..why mess with
the factory zo6 springs and pushrods..the comps aren't that expensive and they match your cam.

Re: Ok, Valve spring/pushrod/lifter question... THe LS6 springs, identicle at some point to the HotCam kit springs, were supplied with the 217/227 .525 .525 112 hotcam. Seems to me that unless the ramp rate on those lobes is pretty extreme, it should be able to control that cam quite nicely under the stockish <= 6200 rev limiter.
