The '65/'66 intake manifold can be used on all Pontiac V8's through 1979 except the 301, 265 short-deck versions. The heat riser passage and casting recess adjacent to it on the later heads is larger than early heads, so you need the proper year gasket set, which takes care of the mismatch.
Thank you sir !
