I looked for some photos of the oiling mods to help you out but I couldn't find any. I probably can't remember them all but I'll try. Big thanks to Todd Marsh and Ray Barton for helping me through that fiasco. First of all, all four of the holes in the block that drain the corners of the heads, were undersize from stock. So I had to order an extra-length drill bit of the proper size and drill them out. Next, there is no oil drain in the lifter valley, so I drilled holes down the middle of the lifter valley, the size and spacing that Todd and Ray told me. Then there is no escape for the oil to the front cover, so I used a hole saw and cut a 1" hole there with the bottom of the hole being flush with the lifter valley so it could drain there. I hope that was all of it.

I didn't notice a cooling problem in my very limited driving at the track.
