Hey boys, In the process of building my N54 at the moment, and was wondering what headgasket to go with. Currently I've acquired Manley turbo tuff rods, JE 9.5.1 pistons, 11mm headstuds from Vac, King main and rod bearings, with the updated bmw crank hub design. Shooting for a 800whp setup, not looking to run it there at all times though maybe a few pulls.
