Hey
After responding to this thread I happened to have mine apart this weekend and I gave it a closer look.
I think it might be a symptom of the pushrods being too short, like its not compressing the plunger past the weep hole or something, so the lifter bleeds down and then there's a little slop in the valvetrain.
To test this theory I installed some comp cams 6828 pushrods (they are .33 longer than stock. Lo and behold my car doesn't seem to bleed down so quickly and it is quieter.
Obviously I am going to check into getting some longer ones still, but thought I would spread the word. Checking pushrod length with pedestal rockers sucks, btw.
