carnut,

someone mentioned in an earlier post that BB Chevies have 5 bolts around each cylinder; they do, except for one cylinder on each bank, which would have to go through an intake runner in the head. They did on the all aluminum ZL-1, with a cap on top of the runner for access to the head bolt.

I thought the Zl-1 employed 2 studs in each head that go into the valley on each bank like the late Hemis employ 4 studs in each head that go into the valley on each bank. Are you sure? That's the first time I've heard of a cap on top of the runner (s) to access a head bolt (s) on the ZL-1.
