Custom ground camshaft, low power

bad news. I had similar results with a hot engine. Right around 20%. I couldn't tell before but when I did the test this time it was at night and alot cooler and I could see quite a bit of steam coming out of the carb when I would put pressure to the cylinder. I had the same results on the #1 and #2 cylinders. I still couldn't really notice anything on the exhaust side. When I pullud the cap on the coolant to look for air bubbles I noticed a few drops of oil in the radiator. I think I'm gunna pull the motor and run through it again and check everything out. Hopefully I just need some head gaskets. I'm going to go ahead and do the test on all cylinders so i know where I'm at before I pull it out. Is it a possability my rings aren't gaped right? What could cause my intake valves to leak but not the exhaust.
