Re: boost heads

At 25psi I would get ARP hardware and a new head gasket. Below 30psi stock head is fine.

Re: boost heads

Stock head studs will easily hold 15 psi on just about any turbo.

Re: boost heads

Sounds like he is asking about the head itself. All DSM heads should be good for several hundred psi.

Re: boost heads

Holsets are nothing special, though I like the one on my cummins turbo diesel. There are many DSmers running large "regular" turbos (garrets) that have to use 50 psi blower guages
