Yep.
These seem to be holding up so far to 15-20 psi of boost in my BMW M30B35 engine.

It saved my boosted M30B35
I can increase the boost upto 1.2 bar without any problems. And the gasket is a factory original one. thanks...

Fitment issues but do the job
These head studs are great for boosted applications on the BMW M30 series of engines. However, they lack the shoulder on the stock head bolts that locates the rocker shafts. This means that the rockers could slip off the cam, and do a bunch of engine damage. Also, the valve cover must be ground down to fit over the taller ARP studs. Unfortunately, there aren't many other options.
