How much boost with just ARP headstuds
How much boost can a 12 valve hold with just ARP head studs an a Cummins headgasket? I've been reading mixed things.

I've hit around 50 maybe a touch over on the dyno on no2 and I'm sure my drive pressure was around 70. They are supposed to hold about 80 psi from what I've seen. Some even claim higher.

50 psi and 70 psi drive pressure is pretty good on no2.
Alot comes into factor when you start talking about lifting heads. drive pressure really comes into factor. It would be hard to say 58 psi you are good 69 psi and hg is going to "pop" |
Thank you, I'm thinking about fabbing up a exhaust manifold. Because now I'm very set on doing a Twin turbo setup in order to control the EGTs on this truck. I don't pay for anything since I'm in the barracks so i just save up money while my truck sits at home. I've been doing reading on what my options are for the twins. I'm pretty good with tig so I 'm thinking of doing the piping myself. Vannest's shop has head studs that he custom orders that he swears by they are suppose to be better than the ARP studs and he gets them for cheaper. They're also USA made in a steel mill in WV where we're both from.
