? Valvetrain Geometry ?

I've been in a battle with a good friend of mine whom has built a few high-performance engines. His arguement is pushrod lenght makes a difference and I said rocker shaft placement limits the actual sweep of the tip. Score one for the old guy..... I guess I'll order some shims and play with it at a later date. As for now, I picked up a set of stock rockers, shafts, and push rods yesterday. I'm headed over to the garage in about an hour to install it all. My mistake was not checking the actual roller movement across the valves when I had the engine on the stand. These mistakes is what eventually becomes experience..... Thanks for everyone's input. I measured right, just skipped a more important step first.

Hopefully later we'll have video of a happily running small block...... 8)
