Ive got a 67 cougar with the original 289 with 289 heads. i just had the heads redone and installed a new camshaft. new pushrods , etc. how do i set the valve lash for cam break in and how do i set after cam break in? (still using original rockers). thanks in advance.

The only thing I remember about my 302 was the rockers were a "torque and go". No adjustment, so to speak. The rocker pivot bottomed against the stud and then it just got torqued down and it was good to go.

You have adjustable rockers so heres what you want to do,turn the engine over so the valves you adjust are in the fully closed position,do this one cylinder at a time,turn the adjustment nut down and rotate the push rod between thumb and forefinger while adjusting when you get to the point the pushrod no longer rotates add a 1/2 turn.A lot of people and books will tell you 3/4 turn but I have never lost a cam on break in doing it this way as that allows room for lifter pump up.Don't forget use Shell Rotella oil for that cam break in too,there are some excellent posts on here about that too!

thanks Jeffb, but i have a hard time telling when the valves are open or closed..ive got a mild cam so its hard to read them.. is there a formula for setting certain valves at tdc(compression) then turn the crank 180 and then adjust the remaining ones? thanks. or maybe a guage or indicator to check valves, to see if they are open or closed.?

I've always done this by eyeball,watching the rocker arm position to go by, when they are up and there is some slack.But,thats something you can do from years of experience.You might want to go by sequence so I am suggesting you join this website and you will learn a lot about small block Fords. www.sbftech.com
