Also if you are running a separate coil then you don't need the HEI ignition which has the coil on top of the distributor.
If you don't care about that, then get the one you have listed above, with HEI and a vacuum advance on the base. Also if you are using the GMPP Carburetor Manifold (http://www.jegs.com/i/GM+Performance...02592/10002/-1) you can just buy a normal MSD distributor or even a ACDelco one, you don't have to spend the extra money on a billet distributor. If your heads have been milled or the block has been decked heavily the bolt holes on the intake may not line up perfectly. Also you might need a shim or an adjustable collar distributor if the engine has been machined heavily to make sure that the distributor gear right and the collar on the distributor sits right on the manifold.
