Went for a 40mile drive today. Everything went fine. Good oil pressure no overheating, no strange noises no smoke. loud as hell!!!! Good power in the power band and i can easilly feel the extra torque.
Got home and did find a fairly significant oil leak on the intake side, im hoping its a crush washer issue or something near the filter housing. Ill investigate soon.

Great write up! I love your attention to detail. If I ever end up rebuilding my engine again, I’ll be going back to reference your thread.

So far shes doing ok. Have about 60 miles without major issue. Definitely feels powerful and runs smooth. It does have a significant oil leak i believe from the oil filter housing. Ill check into that soon. Im almost certain its not from any place bad like the head or oil pan or anything like that. Changed out the break in oil to Liquimoly 10w60 synthetic. Rechecked leakdown on cylinder 3 its still at 8%. Seems like thats what its going to be....it blows out the oil cap too so i guess ive got a ring sealing problem on that cylinder. Any thoughts about what to do about this if anything??

Hi, yeah as far as i can tell the oil filter housing was the source. Its nearly impossible to tell for certain before removing the ofh and then oil is everywhere. I did use a gasket there that was sitting in my garage for a few years. I guess it must have hardened from sitting. I put a brand new one in and it seems to have resolved that leak.
Another leak presented itself off the back. Seems between the head and block but its of course in an impossible place to get to. Luckily its very slight and since i dont drive it but on track it should be manageable. I plan to do cams in the next year so ill pull the head and see whats going on then.
As far as the leak down numbers i havent repeated in a while but i can report that i took it to sebring in january and it ran flawlessly. Apart from very worriesome white smoking in the morning warmup, which completeoy disappeared omce warmed up it ran perfect all day. Power felt markedly improved, smooth acceleration, and sounded great. No issues with temps, and oil pressure was fine.
Im going again in april and ill rechceck compression and leak down during my prep and see where im at then.
