Riddle me this!!

[steter12]

I have 1990 OMC Cobra 4.3L with cracked one piece manifold....I ordered the two piece conversion kit like I was instructed to do. My one piece mans. have 4 bolts and the new replacements have 6....I am positive this is the replacements from osco for the omc one piece....did I get the wrong parts?
Even the illustration on the website shows the old discontinued mani. with 4 holes and the replacement with 6!!!

Other than the bolts do they line up...look at the gaskets compared to the heads...

The old batwing style manifolds only used one bolt on the 2 front exhaust ports.
The head should have the threads for the extra 2 bolts..
