Ultra pro mags do not fit Manley 1.55 springs

[tleed]

My comp Ultra Pro mags don't fit with my Manley 1.55 springs unless I make the push rod insanely long then they ride on the outer tip of the valve does anybody know of a good set of rocker arms that will clear the springs Has anybody else ran into this issue?

Where is the interference? If it's in the raduis where the body of the rocker and arm is, I have seen the rocker clearanced (ground) to fit. Doesn't take much but not for the faint of heart.

Yeah its in the radius that's what I thought just hate to take a dremel to a new 300 dollar set of rocker arms I wonder if Crower enduros will fit without clearancing

What model ultras are they or ratio, stud, sa/nsa. There are several rockers that will clear 1.55 spring.
If you go to summit and bore down into options far enough it will finally give you a max spring diameter option.
It should be there at the very top since it is a critical spec but their option structure is realy goofy for many part types.

1605-16 7/16 1.6 nsa comp says they will clear 1.55 springs but they do not in this application
