OIB63 4 Posted July 5 Were the manifolds on 64 Riviera 425 painted and if so what color? Thank you Share this post Link to post Share on other sites
RivNut 2,954 Posted July 5 The entire long block, including intake manifold, plus any brackets secured by bolts that were torqued prior to the test run were painted. All nailheads in 1964 were painted "Buick green." Exhaust manifolds were not painted but they can be treated so they don't look too rough. There are discussions about exhaust manifold treatments on tbe forum; just search for them. Share this post Link to post Share on other sites
