My '72 LT-1 has an L-82 cam installed. If I switch back to the original cam and solid lifters, should I replace the pushrods, as they may have formed a fit with the top surface of the hydraulic lifter, and therefore not be compatible with the new lifters, and cause premature wear?
And carrying that thought forward. would new pushrods require new rocker arms for fit compatibility at the top end; and would new rockers require new valves for fit issues there.
The engine parts were new GM when installed, and have 17,000 miles on them.
It seems to me as if changing the rockers and valves would probably be excessive, but that the pushrods might be a different story, so I wanted to gather some opinions more educated than mine.
Thanks in advance!
