So it was running strong, and things looked good initially. Then, oil everywhere that didn’t make sense. Coming out from under the valve covers, but little from the breathers. Compression/leak down test was great. Turned out the exhaust crossover had burned through the gaskets(felpro 1213(not s3)), and was blowing exhaust straight up under the valve cover lip. I believe a need for a thicker gasket contributed to the problem.
Unfortunately, I only figured out the above issue because shortly after it was stumbling and I had a dead cylinder; #8.
