Cosworth do stainless steel ones with a stopper layer around the bore.
Not sure if yours have those already ?

Running that boost with ARP studs and Subaru MLS head gaskets shouldnt be a problem tbh.
Be worth checking the ARP studs for stretch or if they are loose when you remove the head nuts and washers.
Check the heads and block faces for distorsion/warp when its apart.

well its looking like its not my heads going as my engine builder and tuner has had a good look at it and has advised me the thermostat i have put in is just not working good it was and after market one the fans were coming on but not colling it down past 94.5c and we think the thermo sat is not open but soon as i drive it drops to about 89-90 c so im going to try this zero sports one and see if i can sort the problem out, ps my car has not ever over heated some times these tuned subaru ca n be a reall pain in the behind
