This afternoon I called Dave at TRF Tech Support, He is EXTREMELY helpful!! He told me some information that he had written down quite a long time ago concerning how the cam bearings are to be located in the block housings. As a result, we concluded that my cam bearings are installed in the correct orientation with the right holes in the right places, except that the hole alignment could have been a bit better.
Here is the information that Dave told me:
1) The oval hole is the one used for the locating/retaining bolts and as you look at the front of the block with head at the top, the hole should be oriented at 3:00 o'clock.
2) The small round hole is the main bearing feed and as you look at the front of the block with head at the top, the hole should be oriented at 8:00 o'clock. (Note: we could not determine a use for the small hole in the narrow cam bearing.)
3) For the middle cam bearing (by the middle main bearing) the large round hole has no purpose and is probably blocked. Although Dave did not have it written down, we concluded that for the back cam bearing the large round hole is the rocker assembly feed hole from the head, and the orientation of that hole is 10:00 o'clock. We assumed that the large hole is put into both of the wider cam bearings to allow the installer to place them in either the middle or to the back so no worry about which one to use.
Jerry, the new cam bearings get pushed in using the special tool and it also pushes out the old cam bearings. No need to ream anything. Although my machinist did verify that the new cam bearings correctly fit on the new cam before he installed the cam bearings.
Hopes this helps!

Bob
