Krazykuda thanks for the list of threads. I have read most of them previously and am planning on contacting oe pushrods when I have better idea of the length needed. RRR thanks for the lead on the crane push rods. they they have a "working length" of 7.185, the Melling mpr-157 are 7.234. The .049 difference may or may not be what i need. As you can see from the photo this is how close the cup is to the rocker after setting the adjuster to zero lash plus one turn as per Racer Browns instructions. Also the cam is a Racer Brown EH-20 dur. @50 i220 e220 lift i.450 e.450. The geometry looks correct with the 7.234 push rods,
