You guys are good.

The previous owner had the heads shaved a couple mm's to bump the compression, so that shortened the crank centerline to the cam centerline. The chains are probably OK and probably within spec.

I spoke to three engine builders today and all three suspected the engine had been shortened somehow. Jerry Woods said this was common in the late 70's/early 80's on race motors (along with mechanical tensioners) and that's why he makes idler arm tensioner wheels that are 1 and 2 teeth oversized. Good call Tinker - I am going to replace the wheels. After all, if I split the motor, install new chains, the same will most likely happen within 5000 miles again without the new oversized wheels. For your info, all three builders said installing master link chains is a good option too, but it would not solve the problem.
