Apples to a closer Apple would be the the 600-13 VS the B1-TS heads both on a 4.840 bore spacing both can have the 2.45 Int valve.... The TS will be on the upper hand for sure in that case.
Really what everyone wants in a head for nothing. A heads that flowed 450+cfm that you can put your 906 rocker gear and valves in.....
We might be at a disadvantage in many ways but when it comes down to it, you say a Horsepower range you want your engine in and there is a head that will do it. Cost is another thing but the heads are there. Even if some are dinosaurs. (Even if most are dinosaurs)
I forgot who made the list of heads here on the post but he missed a few (PSO, Brewer, TS) with even more overlapping hp possibilities and then he didn't mention any of the Hemi heads out there.
