Whats a fair price?

The heads are worth $50.00 to $75.00 for the pair. Most people will regard them as cores, and there is the inevitable chant from others that why mess with them when for a few dollars more (after fixing/rebuilding) they can have new aluminum, or EQ iron. The intake is good for $100.00 to $125.00; again the inevitable chant is the Air Gap is better bla, bla, bla. Actually I kinda like it, have one on my "Mean Teen" (318).
