Rickster 1,
There are sources where you can acquire the components for a cammer build, but the numbers being thrown around are pretty accurate. one of my sources has a set of original aluminum heads...only 8 grand...bare of course, or he can set you up with a cast iron set for a little over 4 thousand. A properly machined block? New or original? He is modifying a Pond aluminum block right now for a cammer build, that is easily another 7 grand. Have you ever priced an original set of magnesium cammer valve covers?
If you are prepared to fund such a build more power to you...I would tell you to go for it. Unless you are an expereinced FE builder I might suggest you leave the engine construction to the guys that do it for a living, the cammer especially is a beast unto itself. If not, once again, try it yourself. I would think it would end up costing you more in the long run due to having an expereinced builder fix the mistakes of a first timer.
If you need a parts source of want to talk with a builder who can put the real deal together for you send me a pm and I can put you in touch with some quality sources.
