Machine shop.  Shouldn't cost too much if you can find someone to do it.  I had a buddy that use an angle grinder but that's pretty sketchy :).

You could just run a stock cam and not have to worry about it.  Gnarls on here ran some pulls on a bunch of cam profiles on some kind of desktop dyno and the stock cam profile isn't exactly bad unless you are going with a really nasty cam.  The stock cam makes more bottom end, has a really broad torque sweet spot and wraps out pretty well too. I am running it in a 20r/22r hybrid and after some tuning with an adjustable cam gear and getting the carb freed up and dialed in I am fairly impressed with the whole setup over a stock 22r.  It's not a 3RZ but it's getting there.  I can tell you if this engine was in a smaller, lighter pickup or a car it would absolutely rip!


Here this thread has a whole bunch of spreadsheets in it that Gnarly posted up.  I think some of the later ones even had the 20r data in the hypotheticals:  http://board.marlincrawler.com/index.php?topic=100575.0
