Randy, this may sound dumb but what are the cam followers? I am looking at the parts manual and do not see a part labeled cam follower.

Hello Curtiss, the part Randy is referring to is in the attached photo, the cam followers run on the camshaft and lift the valves, As Randy stated the cast mushroom shaped heads of the followers come loose in the stems sometimes, I found three loose on my build. The followers are in the follower block, there are four of these.

I just got the head off and it is looking like I have a pretty solid scoring in the rear cylinder and the top of the back 2 pistons had a thin coat of oil on them. I also noticed an inconsistent color in many of the valves by cylinder. I am done for tonight :(

Well I dropped the oil pan tonight and removed the rod cap on number 8 which is the cylinder I had scoring in and sure enough the second ring from the top was broken.

I looked at the Rod bearing and as I was told by a previous owner the rod bearings have been converted to inserts but they were in pretty bad shape as was the crank. I was at least able to get number off of the bearings so I can get them replaced.

Now I have to lean how to decode bearing numbers :)

I think you are missing the oil drain back tube on the rear main.
The bearings are .020 undersized and were made in 8/06.
