So heres one more thing I don't know. They installed adjustable rockers but now they want to put in custom pushrods. Using speedmaster PQX 3244011. Are the stock pushrods usable with the adjustable rockers?
Well, I usually take the stock heads, pushrods and rockers and throw them in the trash, but as I remember the stock rockers on all (or nearly all) RB engines were non adjustable rockers and the pushrods are rounded on both ends. The adjustable rockers will have a ball in cup style adjuster.
