Still waiting to paint the aluminum intake manifold before I take the cast iron one off. Advance auto had to order the Duplicolor high temp engine paint that should be for an Olds 455. Have to keep things authentic. I get stopped so often at gas stations with inquisitive people wanting to see my vintage coach, I'd be embarrassed if I didn't have the authentic Olds blue paint on the engine.

BTY, Head is still on. Will announce the cause of the low compression as soon as it is discovered. The replacement head is at the Head rebuilder for the second time. This time the head is getting the divider (web) between the inside exhaust ports welded up to the gasket surface. Hopefully, this will help the header pipes produce even exhaust back pressure and cooling and keep my Remflex gasket from blowing out a third time.
