More machine than man
I just got some brand new full roller rockers from Howards Cams (Part 90084) and I am not sure if they are OK or need some break in time? Most of the tips all roll really easily and smoothly by finger pressure, but the tips on 3 of them don't seem right to me, they are stiff and gritty. Is this me being paranoid about my first engine build or do I have a concern? I called Howards and they said no problem send them back, but I would like other opinions on the matter. Thanks!
