New rebuild....but tic..tic...tic

Take your valve stem to rocker clearance then divide that clearance by 1.5. THEN add it to the desired preload.

Example: .045" stem to rocker clearance / 1.5 = .030"
.030" + .070" preload = .100" longer pushrod

-did not measure new cam vs old (seems reasonable I have a stackup tolerance issue)

-.075 longer?

nm9…I see your calc dividing by stock 1.5 rocker ratio, so if my adjustable pushrod is adjusted to ZERO lash and I get the same approx.. .040” longer /1.5 + .080(recommended) =.106 longer pushrod =(7.606)

Based on above theoretical example, I could get a set of 5/16” -7.605 (Ford 302) pushrods and I’m good to go.

Should I measure every pushrod or can I just go with one intake and one exhaust?
