I wont speak to things im not sure of, but I know one thing. If you use a crappy "twanger" style torque wrench when u tighten your heads down, you'll be sorry. I was :) Use a QUALITY torque wrench. If it costs less than $100 bucks, its junk !!

Get the heads and block surfaced and true, get ARP head studs, and a good gasket set. Should do ya good.

Getting proper torque on used head bolts from a supercharged engine can be a bad thing. Bolts actually stretch etc... when detonation occurs, high heat etc... If you are not going to switch to studs, use new bolts each time.

I can't imagine why with only 9 pounds of boost you are blowing gaskets.

Either the bolts are bad (from being over torqued), the deck or head isn't flat, or you are not torquing the bolts properly. Out of the three I'd bet bad bolts or improper installation torque.

I have no problems at 8-10 pounds boost and 500 or so horsepower using Felpro gaskets and ARP head bolts.

I use a click type wrench but I check the calibration periodically with a bathroom scale and bench vise.

Probably stretched head bolts. The stock bolts are crap anyway.
You'll want forged pistons, and then the cam is the LAST thing to get because that depends on the rest of the engine such as the heads, intake, exhaust, compression, rear gears, transmission, etc. Everyone goes for the cam first when it needs to be last on the list.
