Anti Pump Up Lifters & Roller Rockers
I have new anti pump up lifters to go with my hydraulic cam but apparently I will need adjustable roller rockers to be able to set a .0002in gap at the valve tip.
Can anyone recommend a cost effective solution/brand/source of parts for roller rockers.
I presently have non adjustable Yella Terra roller rockers that are adjusted by packing shims on the pedastal to set a .0020in to .0060in preload on the standard type lifters and it would be a lot of fiddling(read nearly impossible) to get these to a .0002in gap at the tappet.
I have done a lot of research on these anti pump up lifters and some manufacturers(Federal Mogul) are recommending them in place of solids for all round performance engines so I don't want to go with solids or hydraulic roller lifters.
The cop said "Do you know why I pulled you over". I said " Well, that all depends on how long you have been following me!"
