Pull the valve covers & Right on top for the date codes,I think.
Some castings were around the sparkplugs area.

They aren't really that hard to miss.

I found the casting # its D7OE it was on the bottom of the head
the block is D4OE-6O15-BA
the heads have adjustable valve train I though they stopped in 1969
can any one tell me what cc.the heads are and c/r it is the pistons are flat tops with four valve reliefs in them
I also dont know what the engine came out of.

Because the heads are a '77 casting and the block is a '74 casting its had some work done to it. In order to determine the CR we need to know if its been bored and decked. A stock configuration engine (ie. stock bore, stock deck height) would have a CR of about 9:1 provided the heads have a 60cc combustion chamber. I know of 3 different combustion chamber sizes for 302's: 60cc (most common on earier heads), 64cc (on some newer heads) and 69cc heads (least common). I never heard tell of the 69cc 302 heads (69cc is common for '71 to mid '80's 351W heads) until I acquired a 302 that came out of a truck. It had 69cc heads and factory flat tops.
