I just think that by the time you spend all that money on the head, including the studs and gasket, then get custom pistons, and pay for an injection pump of some sort, plus the cost of fitting it somehow to the 300, you'll have been able to by 2 6bt's out of a junkyard somewhere.

That, I can agree with. I'm not sure how much you think I'm going to be spending on the head, though. A new head gasket is cheap, studs aren't expensive either. The injection pump is the most cost-prohibitive part, along w/ the injectors, but I can get IDI injectors from a 7.3 International (From a F-series) for a few bucks a piece, and the injection pump may not cost me that much, either, if I can get one from the junkyard. (Around $30, IIRC.. they have diesels come in once in awhile.)
I'm still looking at the old-school air injected diesel thing, though. I dunno if I can make it work or not, or if I can simplify the design just enough to make it work.
Beyond that, the pistons are the most expensive thing... and with any luck, I'll be able to find 4" pistons in a diesel somewhere that are close to the right specs, and work around it from there. Pistons are also fairly cheap, as long as they're not custom made. If I have to get custom pistons, I'll just wait until I get my mini-forge setup (which could be years, further delaying the project) and cast some myself. (Yeah, I can cast/mill metal, when I have the tools to do it.)
