Don,

I think the 65's were mostly black.

By far the best engine paint I've used is POR-15.

I painted my block according to their recommendations and it has held up perfectly.

Start with a coat of their standard POR-15 rust resistant paint and after it sets up the proper amount of time, but while still slightly tacky, brush on a coat of their high pigment engine paint.
It is self-leveling, very glossy and very tough.

I clearcoated all my aluminum parts with POR-15 Glisten PC. It is a 2-part urethene which is also brushable and extremely tough. It has even held up on the heads, although it has turned a bit gold around the exhaust ports.

Later,
