How do I fix this? What causes this? The retainers too high? The pushods the wrong lenght? And if I fix the problem can I still use these ones. this is the worst one.
Hmmmm. They should have enough clearence. Are the rockers close when you bolt them down? Can you see that they are hitting?
I have ground off some material on the bottom of some Ford Motorsport Blue rockers before but never the Magnums. Might have to try another set of rockers.
You would have to make the call on if the retainers were OK or not. As long as they are not damaged in the critical areas then I would say you should be OK.
Do you know someone who could lend you some other kind of rockers just to see how they line up?
Which magnum rockers do you have? There are two types one for rail rockers and one with out rail rockers. Qucik way to tell is to look at the part of the rocker that dug into the retainer. If that area of the rocker that holds the roller is rounded you have the right one. If it is not rounded but boxed you have the rail rockers which are incorrect for your app.
