The one thing we have not mentioned so far are the pushrods. Since each motor can be different, it's hard to include a correct size pushrod with so many variables. The ones we used were supplied by Speed-O-Motive, and measure 8.050-inch on the intake side and 8.100-inch on the exhaust. Since this is now a solid roller motor, Jeff set the initial/cold valve lash to 0.010. Then he fired it up, let the engine come up to temp, and re-adjusted them to 0.016 lash while everything was hot.
