FAQ:
Q: Will stock pushrods work with stock lifters?
A: The stock pushrods will also work fine if you have not machined the cylinder head or the block deck. The stock rocker arms can be installed by simply tightening the rockers in place properly with the pushrods aligned. If the lifters are not “pumped up” with oil, there should be no coil bind or valve-to-piston interference.
Q: How do you adjust the preload on a lifter?
A: The only way to “adjust” lifter preload is with the correct length pushrod or by grinding off the valve stem tip to establish the correct valve stem height and plunger position in the lifter. If you want an arbitrary pushrod preload length, most use a figure of 0.020″-0.040″ depending upon the lifter manufacturer’s recommendation.
Q: What size lifter plunger for stock lifters?
A: Once the lifters establish zero valve lash, the lifter plungers will stay at that height within the lifters. Stock pushrod length for your engine is 9.640″-9.660″. 9.639″ should work just fine. As for valve springs, the stock springs should work with the stock cylinder head (no head machining or changes in valve stem height).
Q: Does valve stem height affect lifter preload?
A: When valves and seats are ground, the valve stem height is crucial. (Milling or surfacing the head will also alter the valve stem height. So does installation of a thicker or thinner head gasket.) Valve stem height affects the lifter preload.
