about 2/3 to 3/4 the way down they show a Jeep cylinder head, and the 'new' head has a much better head design in terms of quench compared to the old style open chambers. Is that 'new' head a factory Jeep casting, the newer ones with small exhaust ports, or a HO head compared to an old 258 or renix head?
Any info would be interesting to know. -Matt
