It's interesting that no one on this site has mentioned his other new parts such as the H.D. replacement 312 connecting rods, advertised in issue #88 of YBM. All focus seems to be on the Heads. In my humble opinion, say a person has already paid for performance reworked heads for a street machine. According to Mummert in past articles in YBM, flow tests have shown that even a somewhat reworked "B" 4 bbl intake, is definitely a restriction to cylinder head flow, on well reworked heads.. So, unless your are seriously into racing, the new Intake Manifold (despite my reservations about no choke heat availability!) would likely be a better investment, at an introductory price of $369, rather than spending $2100 on new heads.. Yes ?
