Mopar Small Block Head info:

Just my .02, John...but by the time you pay for a decent set of J's (most likely you would end up with the 1.88's as they only made the 2.02's through '71) and have them upgraded to 2.02 intakes and have the bowls and ports massaged...you'll likely be close to, or exceeding the cost of a set of Edelbrocks. Summit has them for around $750 each now. They come ready to run with 2.02's, flow better than cast heads out of the box, and weigh about half. They also have the 63cc chambers, which would boost your compression a smidge over the 65cc J chambers. They would top your 360 very well and tend to cool faster than cast iron heads as well. Again, just my .02...
