Installed my built head a few weeks back. It had been sitting for a while so i did not bleed lifters before puttong head on. Engine ran nice and wasnt noisy at all. For the past week ive noticed some rattle noise, light at idle and increases with engine speed. Well, i pulled the valve cover today and start poking away. None of the rocker arms compress at all on the lifter side.

This has me stumped as it is a high and light sound under the valve cover. The other thing i noticed it what looks like carbon buildup on a couple rockers and cam lobes. Ill post a picture as im not sure what i might be looking at.

This head is build to the golden sr head specs. Only thing not in it is solid lifters.
