Thanks.
Rebuild costs are relative to machine shop labor required. Let's assume everything is in spec (it won't be) then you're looking at at least $1,000 in parts if you plan to replace everything (bearings, pistons, rings, gaskets, seals, valves, guides, etc.). You can cut several hundred off the cost if you can re-use your pistons (but really, get some slightly hotter pistons and you'll have a nice fast Spider). Then increments of $100 for various types of labor - cutting bores is around $200 at my shop for 4 (not relining, that's $150 per bore) - tanking and jigging in that aux bearing - guide removal and replacement - surfacing - cutting new seats - and so on.
There is a lot of really junky stuff out there, and if you plan to be skimpy then expect a 2 year engine. Use a good vendor and discuss what you plan to do, options, etc.
Twin cams are easy to rebuild if you are clean and careful, can measure things, and know better than to guestimate. Machine shops can measure everything up and tell you what pistons to get (once you tell them what is available size-wise) and they'll cut to your pistons. Part of the fun is building these things yourself, so plan on the tools you need (a good torque wrench, engine stand helps, rent an A-frame to pull it, etc.).
