usually when it comes time for headers. I always recomended that any headers be fully welded up around the tube, and then ground to match the port opening. I dont have leaks anymore, and wont do it any other way. There are three distinct ones that you showed, plus the differences in the roof, bowl, guide area, of these, and also the different 427 heads. I believe I remember 9 different exhaust ports altogether, when making molds of them. The Cammer exhaust port was the all-time flow champ of any motor that came out of Detroit, topping the Boss 429, and both styles of the Hemi. I wonder what the M/T Hemi heads would have been like? They were a big improvement over the 392 heads that they were patterned after. I have cross sectioned photos of them, but never had my paws on any. That was then, this is now, and there are some awsome ex ports on the market today. I prepped some Canfields before, and they were excellent, much better than the Brodix or Edlebrock's. |
