One of the many issues is the quality of the lifter, especially, materials and sizing. The sizing problem creates issues with lifter bore clearance and also when the lifter does not have a crown and the lobe does not have a taper.

It does not matter if the valve spring pressures are restored to the old rules. Too may engine builders are seeing camshaft and lifter failures even on mild street builds.

There is only one lifter manufacturer for solid and hydraulic lifters left in the USA.
