I think you are greatly over stating what affect more lift has on your valve train. You dont need HUGE springs, and the comp cams dont have HUGE lift. Most of the comp cams run around .533 to .540 lift. That is not HUGE by any means.
Comp like to run more lift because that what roller cams are good at. Thats what their advantage is over flat tappets. Factory computer controlled engines can have driveability problems with lots of duration, so why not take advantage of extra lift the roller cam allows?
Most aftermarket heads can handle at least .575 lift. Dont know about the P heads, but if they cant, then you should upgrade the springs anyway.
XE cams arent hype, they are proven performers. Might not be the best choice for some crappy springed P heads, but stronger springs are a wise upgrade on any mustang, even a stock one.
If a heads max flow is at .500 lift, and you go slightly over that, say .533, wouldnt you be spending more time at the .500 mark than a cam that has say .490 lift?
