JBA makes some nice headers for the 2.9L. I had them in my first Ranger, and the difference was amazing. I saw an article at "The Ranger Station" on how to make a full floating valvetrain for them. I did a search and found:
This tip comes directly from Sven Pruett's book How to Build and Modify Ford 60 degree V6's. If you really want to do this tip I highly recommend that you get this book, I beleive that Vanir still carries it. This weeks tip is on free floating rocker assemblies. This sounds pretty exotic but its really a pretty simple mod that will cost you probably under 200 bucks, got mine done for 150 I believe. The parts required to do this modification are new rocker shafts, Aluminum to be made into spacers, possibly new pedestals if the old ones are pretty worn, and some new roll pins, and last but not least a good machine shop. The modifications include changing the rocker arm to shaft clearances by quite a bit, chamfering the oil holes in the shaft, running aluminum spacers instead of the springs, and thats about it. now I will give you the specs.: Shaft to rocker arm clearance .0025-.003in. (stock is .0013in.) rocker arm bore diameter should be around .7836-.7842in. Aluminum spacer to rocker arm side clearance of .010-.015 for each roker arm that, that spacer is used with so .020-.030in. for the rocker arms between the pedestals. (stock is 0 clearence between spring and rocker arm, it actually rides up against it). With the increased rocker arm to shaft clearances and now a clearance between the spacers and the rocker arm, along with increased oiling to the upper valvetrain. These combine to create a very slick and essentially pretty friction free rocker movement, in fact after the valvetrain is reassemblrd you should be able to flick one of the rockerarms and have it spin arount the shaft numerous times. when compared to a stock rocker assembly its night and day in fact you will probably hurt your finger trying to flick one of those due to the springs actually exhurting pressure on the side of the rocker arm, and the very tight clearance of the rocker arm to shaft on a stock rocker assembly will tend to drag a little. The thing that surprised me the most about it was how much I improved my upper valvetrain oiling, on most 2.9's I can adjust the valvetrain with the valvecover off with the engine running and barely lose any oil spilled off the heads, On mine with the free floating rocker assembly, I tried it once and pumped about half a quart of Mobile one on the ground, I don't adjust mine that way anymore. This modification tends to help most in the upper RPM bands and its a noticeable increase but not as big of an increase as I would say headers would be. Also it seem to rev a little quicker than it did before the change mostly due to the lack of friction in the rocker assembly, and as a bonus they look pretty cool when you have your valvecover off if you run polished aluminum spacers. But if you are serious about doing this mod please get the book becouse it goes far more in depth than I did here.
I know you're looking primarily for internal mods, but I also found that a high performance ignition also made incredible gains. Mine had an Omni Maginum, and the difference between it and stock ignition was almost night and day. Good luck!
