SBC intake center bolt holes

[Shannen Durphey]

Well, my experiences haven't been as high tech as your suggestions. 
I've cut angled spacers on a band saw, hogged the intake holes, and
installed an older manifold on newer heads.  Looked horrible, but it
worked.  I've also ground the snot out of a tbi manifold and installed
it on older heads.  Looked horrible, but it worked.  Total cost?  Less
than pennies, since the air, electricity, and aluminum tubing were
already on hand.
