That manifold looks quite similar to one that I received in 1998 from:

Rotary Reliability & Racing
(Fast Freddy's)
714-839-8018 or 641-2980

They advised me that it was for a 12A, but would work on the 13B with an
adapter, which I received also.  However, in that my block is a 4-port, turbo, it
required a second adapter from Hayes Rotary in order to fit the block.   It
also required some porting work.

Bottom line is the assembly wound up heavy and mickey-mouse compared with
Paul's manifold and pipe bends.

As I recall, the manifold was $200 and each adapter plate was $100.   With a
Weber DCOE and air cleaner it all fits, with the end of the air cleaner just
shy of the tube for the dip stick.

Obviously, before bidding, would suggest first making sure it will fit your
block, preferably without adapter plates.

I believe Dave Atkins offers one also.
