Pushrod length?
Just changed to 1.72 rocker arms on GT40 heads. Do you think I need a longer pushrod? What is the best way to determine if I need a longer pushrod? I have looked at it a couple of different ways but have not come to a conclusion as whether to change.

There is a tool that looks like a push rod. It is adjustable, to give you the right size. You can probably rent one. I am not an expert but there should be some posts on deterining the proper length.

it's not that hard to check...i made a tool with an old pushrod and a piece of threaded rod. then I paint the top of the valve, after you cycle it over it takes the paint off where the rollor makes contact. you just need to watch how the roller moves and how much it moves across the top of the valve.
