My attempt at speedmaster heads and moving the pushrod.

Yes, I bought 15mm aluminum round stock (.600" dia), drilled the pushrod holes out with a 17/32 drill bit, then turned the bar stock down to roughly .532 dia, then pressed them into the holes.
Ok, cool Thanks. I thought that's what was up. If you got the stuff and the know how, knock it out! Are you going to run an offset rocker?
