head gasket ?

[trupster415]

well i'm sure i blew my head gasket . there is a small amout of coolant leak out between the block and head by #5 exhaust port and getting presure build up in the radiator. i was boosting around 40 psi with my old turbo ( hx35w) about 6 months ago then i switched to a he351cw and have only ben able to get around 33 psi max. i dont plan on trying to build any more power than i do know so what head gasket will be good for aroud 35psi of boost???

stock one should hold 33 psi no problem. i ran 42psi and 22* timing for a bit and it held. ive since added studs though.
