I’m measuring for pushrods on my 454 build. The way I did it was got the adjustable pushrod tools, adjusted them to a certain length, marked the top of the valves with a sharpie, put the rockers on, then rolled the engine over a few times. Took the rockers off and looked to see where the marks were on the tops of the valves.
I got them adjusted so that the rockers remove the sharpie right in the center of the valve.
Does that sound about right??
