Hemi spark plug tubes

I have moroso fab hemi fat head valve covers. My combo is brad 6 heads and manton LO ratio rockers PAC dual springs. I have a problem where i have to dent the spark tubes to clear the rockers. But when the tubes rotate they hit and rub thru . Does anyone have a fix? Should i just carry a bunch of spares? Thanks for the help

 

We have the same valve cover and the same rockers on AJ Stage 1 Muscle Heads, we made little rings that take up the space between the top of the tube and the snap ring in the cover. This pretty much eliminates them from rotating if the o-ring in the top is the proper one and also keeps you from having to push the tube down every time you put the cover on. We dont even dent the tube, it will clearance itself (Never had it rub thru tho) once the dent gets bad we just straighten them and keep going.

 

Tubes

Noel Manton makes a moly tube with a billet end (Open or closed) that's a little smaller in diameter, you have to shave your plastic spark plug boots just a little from my understanding, I will be getting these soon.

$30 ea but last forever. Tell Noel I said Hi if you call him.

Hope that helps,
