I'm not sure how you can compare the hi-center wide port heads against the cathedral port heads?
Kinda like comparing apples and crankshafts...not much in common.

It will definately be a nice combo and I'm sure there's lots of potential for aftermarket companies and individuals to improve them, but being that they're so new, they're hard to get your hands on them. Availability sucks right now and I'm ready to build something now. If I continue to wait and wait like I have been for this or that to come out, I'll be waiting forever because there is always new and better things coming out all the time.

Soon we will see results form the new TSP 230cc Edelbrock Terminator heads on a 402. They might be something to look into at their price. Their smaller runner head has been a big topic of interest.

The bigger heads can usually make more power and flow more air so usually it is beter when building a performance oriented motor. You may trade some low end for top end though with a bigger cam and the bigger heads but you will have the potential for more power upstairs certainly.

I'm going to have to send my converter back to Joe at Protorque, tell him what has changed, and he'll build around the specs.
With my old setup (cam only), the converter stalled to 5000+ and I shifted at 7200 rpms. Again, that was on a much milder setup.
