Timer? Don't you mean "lightning whirler"? That took me a minute. At least you didn't call it a "dizzy".
Heads and valve covers look like Cleveland. I bet if you painted the intake blue ahead of the first runner it would look more like that is part of the block.
(Actually a Windsor distributor does not go through the manifold. You can remove the intake without disturbing the distributor. I have done this.)
In the engine picture it looks like the coil is mounted to the water outlet area and the upper radiator hose is sitting on the timing cover flange.
