As far as your original question, I would say from reading the cammer articles on here that the TP is much more user friendly. I cannot really count all the issues I have read about parts & assembling one of the cammer engines on here. Although not answering your question, Royce's reasons for suggesting you build a high riser may be an error if he means factory heads. In factory form, the TP will make more power, all things equal and are no more difficult to assemble, as if anyone could use the word difficult to assemble a wedge FE. Do not overlook a MR for a starting point either. All Ford performance FE heads can be found with battle scars in the chambers, not just TP. They can also be found without issues, some patience is required here. Also, just becasue you can only presently get a factory intake for a TP, they are all great intakes.
If a person had access to a reliable complete cammer kit, it might make it a little easier to get in that game. At present it seems you have to buy the best parts from 4 or 5 different mfg.s, and unless highly modified do not produce like what Barry R. on here can achieve both powerwise and reliably in wedge form. He can set you up with a MR HR type aluminum headed FE that will break every drivetrain piece you presently have in your car, delivered to your door.
