If one wants to build this engine for stock eliminator is the 3933163 aluminum intake available new or would one have to look for an old one? Of the head castings listed, 840,291, 858, and 391are any of these available new? Which is the better head castings? Is the bow tie block significantly better than a regular block? I know in superstock there are advantages to using them, but in stock there is only so much one can do. I did hear the Holley is available new. I would appreciate an answer. Thank you, Jesse
