Polly locks contacting rocker arms

It seems like the polly lock is going to far down on the stud & the nut part of the polly lock is barely hitting the inside of the rocker. The heads are aluminum a429, roller rockers, roller solid cam, the valve lash calls for .014 cold. Checked the valve geometry & it looks good. What can I do to fix this?

Wrong studs.

The heads cam & lifters came out of my friends 514 with no clearance issues.

Sounds to me as though the poly-lock itself isn't long enough and are not the correct ones for those rocker arms.

Engine Works makes a set with a 12 point head they are a little longer than standard locks, they will give the clearance you need. If you cant find local try this guy

Where is it contacting the rocker arm body? Does the rocker slot touch the poly-lock at max lift? Please elaborate or post a picture.

What Rockers? Who's poly locks?

A bit of marking on the sides of the slots is normal. Otherwise, go back and recheck the geometry.
Just cuz it worked somewhee else don't meen doodly.

Thanks for all the help guys. I bought a different set of locks & it is good to go.
