Default Procharger and water loss?

Been losing a little water along, nothing showing up in the oil thank goodness but ran the car pretty hard the other night and when I got back home and shut it down, heard water dripping on a header. Upon inspection, I had water dripping from what appeared to be the rear of the drivers side head onto the header below! Don't understand why, car is running low boost, no more than 12 pounds? Before you ask, block and heads surfaces were checked before assembly, yes these are GM 243 heads but they are held down by ARP head studs. I went back over the head studs recently to check torque and all checked to 80 lbs, which is the info I got online from ARP. The head gaskets are Cometics, where did I go wrong, and what else could be checked? Not looking to remove the top end yet, will try to seal otherwise first. Car makes incredible power, loosens the MT 315's at 55 mph in 2nd gear, at 85 mph in 3rd, doesn't seem down on power at all! Any past history to share, recommendations?

Question

Boost may not have been the problem.. How about detonation?? Alky working?
Data logs?

Alky is working according to the sensors from the pump, but I don't have data logs, don't have any tune software yet, guess that would be a good thing to obtain. Plenty of reads but only one reply, c'mon guys give me some thoughts!

Pull the head(s) before things get worse.

I'd do a system pressure test...4D has the answer. The test may/may not help. The test would most likely be a clue if it shows a leak, in that the gasket is really damaged.
What did the plugs look like?

I'd pull the heads too, much better to take care of the problem in the beginning. Bob

I would go with GM MLS head gaskets. Bob

I've heard people have issues with cometics sealing even running NA. MLS gaskets might not be reusable, but they are cheap when considering the time involved with removing the heads and replacing them.

I'm gonna pull the heads, may even start this weekend if I can get this little welding job behind me.
Any particular place better than another to get the GM MLS gaskets? I thought I had the best with the Cometics, but since then I have read quite the opposite. Thanks for all the replies and advice guys, I don't want to hurt this motor, it's way too fresh and a handful to let that happen.
