Unless your trying to make a buisness out of this, by the time you spend the money on the tools, and read the books, and actually spend the time to learn it your better off just sending it out. Believe me i love to do everything myself and hate sending my stuff out, i rebuild trannys, engines, etc and never ever take any of my vehicles to the shop. But one thing i do do is send out my cylinders to get ported. If you really think about it, and the time they put into the set its really not that expensive. If i was going to start a buisness though, i would get my cylinders ported and just look and see what other builders are doing. Maybe its cheating, but thats how every buisness works, they want to know what the competitor is doing. Sorry for the long babble but we just want to know what your trying to accomplish.
