RAMM wanted to know about this 451..............

But to be fair, by the time you were done with those heads they just said Edelbrock on the ends. They were basically a Max Wedge port size correct which is why you used the Indy intake? So there was a lot of work done to those heads. Around that same time frame Dulcich showed up with a set of prototype Chapman Stage VI heads and blew everyone away. Those were a high port head and they really cooked but of course they didn't last long on the market since the cost was so high and Chapman went under during the big recession. If there was a standard port rule engine contest today I think the Trick Flow 240 head castings could be reworked into a high port version with some grinding and filling. I think they would work as well as the old Chapman heads but it would take some porting skills to make it happen. Not my cup of tea but I bet someone does it at some point.

Dulcich had those Stage 6 Chapmans way back in 2002 or so. The reason the TF's would never perform as well as THOSE Chapmans is valve location. Until TF or somebody fixes the valves opening into the cylinder wall then new castings are kind of the answer to a question nobody asked. A set of RPM's ported can match the TF 240's in terms of power--I've done it. J.Rob
