we still have these produced. we can supply any length needed. however, we find
that most applications have enough adustment in the rocker arm to make it work.
certainly a shim under the pedestal is another option and readily available if
you
order stock length. usually making th epushrod shorter by 1/2 the amount milled
form the head will work. on my daugter's tr6 - '74 with .102" cut from head
yielding 9.42 in case anyone is interested - we used the stock length pushrod
(part #V618) and an S2 cam and still had valve adjsutment. ted
