Dude ive got friends with 400whp+ bseries turboed cars. Using only OEM headgaskets. Are your headstuds torqued right? Make sure when you put a new on its a compleltyey clean surface. and if it continues check for machine'ing problems with deck/head.

have you ever machined your head/block?

just from personal experience i know this caused me issues with my turbo'd sohc.
blew hg w/stock studs, then i had the head resurfaced only thinking the block was ok . got arps and slapped it back on, blew another hg. i was just boosting 5lbs w/ an ihirhb5.

head and blosk was resurfaced, ARP studs torched 100Nm. This OEM gasket is not all metal like others honda's. Honda does not make all steel gasket to this engine

whats the material then?

around cilinders is steel oring made by 2 sheets and between them there is that other material, not metal
