Bought a Van......

Just for fun I would measure the distance from the rocker stud to the valve stem.

You have that other set of Magnum heads measure them and compare them. Just out of curiosity.

I could, but when I replace the Comp roller rocker with the factory magnum rocker, it's seems perfect. Problem seems to be the roller has too much "rocking" on the pedestal. The only way to take the excessive "rocking" out is to tighten the nut on that holds the roller rocker in place but then it pins it against the valve and push rod. Strange....
