What engine combo did you have? Block, heads, lifters, cam? Would be interesting to know.

The hydraulic roller lifters are 9/16" longer than flat tappets. Thus making the pushrod/lifter angle even worse.

I'm running a 383 with hydraulic flat tappet lifter on a MP .509 cam so my engine isn't a fair comparison other than the end results. Below is the wipe pattern on No.1 intake valve.
