    That's cool, thing is do you know how far the shop has machined the head at the bottom face when they did the reinstall? The two may have evened each other out..

    Or if they machined it at all. I think re-decking is only done if needed. As long as the block isn't warped, it probably isn't necessary.

    I wonder if these gaskets can be reliably stacked. Some people have had success with that method. Not sure about doing it on a forced inducted engine, though.

    This is the weirdest thing that some cars have thicker head gaskets then others. I mean, why?

    Wow, didn't even think of that. Interesting suggestion to say the least.

    Did they mill your head? How many CC from chamber were removed with head porting? I always like to get static CR at least in to the mid-low 9s if the compressor is large enough. It allows for more stable and forgiving tuning in my experience.

    I've done that with copper gaskets using head studs on LT1/LS1s but leaking was always a problem. On those cars, we could swap the heads in a few hours so it was less of a headache. How long does a head swap take on the N54? I haven't tried it yet. It is tempting to try removing material from the chamber and cleaning up the port work a bit. Maybe if I ever do large turbos.

    Running 9:1 compression pistons should not affect the effectiveness or spray pattern of DI should it?

    A piston set + nice head studs + PAW head/cams + GTX3582 with the tuning/fueling figured out would make a killer n54 setup and I don't see a reason it wouldn't be reliable with the OEM DME timing/knock/AF safety logic in place.

    The DI should be fine but you'd need more ignition advance of course. You'd make up for that by running proportionally more boost... Click here to enlarge

    Exactly what I expected to hear. Surprised nobody with my same thought process but more money than I has not done it yet!
