Hi Paul Your roller rockers are centered for the pushrod and not off centered, that has an intake rocker and exhaust rocker. If you put white grease on the top of your valves the roller should stay in the center of the stem if the geometry is correct. You may have to oblong the holes in your intake for proper clearance of the pushrod through the intake. Go to the book stroe and find a blueprint book of engines and check out this part. You can due this yourself. Take the intake off before you due any grinding of the manifold I dermial tool will work great for what you have to do. Mark the spots to be removed with felt pen. When finished clean the intake real good and air dry to get any metal chips out of the intake runners or holes. Reassemble, set valve lash depending on lifters, rotate engine 4 turns and check for clearance area in manifold. Good luck take your time, ONLY TAKE ENOUGHT metal to clear the pushrod under full movement in slot. Rick Lake
