Paul and Tom,
      It has been indicated that the manifold will fit
both the 4-port and 6-port engines.I have several 6-port
engines and received a 4-port 13B Cosmo turbo engine only
yesterday.The bolt pattern of the 4-port intake manifold
is different than the 6-port plus has an additional bolt.
      Has this bolt pattern difference been noted and is
a dual pattern possible or will the customer need to say
which engine(4 or 6 port)the manifold is for?

Very surprising Kelly.  The Cosmo engine must be a different animal.  After
some devcon port matching, I bolted my old 6 port lower manifold to my 89
turbo 4 port with no problems.  Let us know what the differences are when
you get a handle on it.
