Roller block lifters/ solids/ rockers?

I’m confused by what style cam you have now, flat tappet or roller.


This is a reground hydraulic roller from Oregon cams "as close as I can get" to a Comp XE 268H. The block is LA "roller" and the heads are EQ (magnum) drilled for LA intake.

Turns out I had a set of magnum lifters I didn't know I had, and the heads / cam / lifters are in. I may change later but for now "I guess" we'll stay with the hydraulic cam

Back to work Wed-Thu-Fri, but hope to get the pushrod length sorted out-----reground cam means smaller cam circle, you knew that!!

I think eventually I will want adjustable rockers whether I go flat, roller, hydraulic or solid !!! LOL

I did find the Hughes article on the subject.............
