You must run long slot rockers on the 351 with that cam Or the rockers contact the stud and break or bend the push rods! I am a little curious as to how they stay aligned. If my memory serves me - the stock rockers have lips on either side of the valve stem contact area that keep them from jumping off to the side ( I cant remember)? I can't see in the pic if yours do! And your pics are blurry And ford solid forse oiling lifters do have a hole in the side!!!!!! You cant tell looking at a lifter if its solid or not!!!!!!!! There should be a hole in a solid lifter side just like a Hyd. and out the top through the push rod and the push rod end of the rocker to get forced oil to the rocker, ball, stud, and valve tip and to flood springs for cooling of springs and lubrication some lifters have holes in the bottom to force lube cam lobes!!

Best way to set Ford HYD. lifters!!!!! Compressed method do not pump them up! See pic posted!
Collapsed Hydr. Tappet Gap
8-CYLINDER Ford ENGINES lifters that are not pressurized yet will have slack and that is expected there is a spec for the actual end of the rocker to the tip of the valve when the lifter is bottomed out...


8-302 (5.0L) and 8-351 (5.8L) Allowable: 0.089-0.193 in. (2.260-4.902mm) Desired: 0.096-0.163 in. (2.438-4.140mm)
