I'm sure no broken rings. They all went in as expected. None were forced into place. I used a set .030 ring compressor (not adjustable).

No work on drain back from the heads. Stock block. As shipped AFR 195 Renegade heads.

I followed Canton's instructions on setting the oil level. It is a 7qt pan. Click here - Canton 15-660. I also used their adjustable dipstick. Clicky Canton 20-850 - "These dipsticks need to be calibrated for each application."

Any other recommended ways to appropriately set the dipstick level? How far down from the crank does the oil need to be? I guess I can measure the distance from the oil pan flange to the bottom stroke of the crank/rods and then measure from the top of the oil pan down - fill with oil while measuring and make sure I don't go above that level (give 1/4 inch extra space just for good measure?)

I did a cold compression test tonight. I ordered a leak down test kit and will do that when I get it. My compression numbers were:

1 - 185
2 - *
3 - 185
4 - 195
5 - 175
6 - 173
7 - *
8 - 178

I couldn't test cylinder 2 or 7. I couldn't get the compression adapter that screws into the head in place due to header interference. Although, these all look pretty good. The right side (1-4) looks a little higher than the left (5-8) but I may have held the starter a few seconds more on that side.
