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.

Just a thought but you mentioned you have stealth heads on the engine,did you bolt them on out of the box?,if you did theres probaly light showing between the valve and seat.I have yet to see a set of aluminum heads (anybodys) that does not need a valve job to be correct,I have seen them run but with piss poor results (leakdown/power) such as yours.
