D8OE Heads??
I have two heads with the casting D8OE in them is there anything special about these?
Also would like to know valve size and chamber cc. Do they flow very good. How much cam can these heads handle?

I believe they are late 70's 302 heads. Big chambers, like 69cc big. Real low compression heads, 8.9 or lower with dished pistons. Valves are 1.8/1.5 or so. Small ports and smog humps. I'd stick with E7's over using these unless you don't have any heads. In which case they aren't terribly bad for a daily driver. The valves are small, and chambers are large, so a rather large lift cam could clear with these.

E7's? Roughly the same size valves. Better flow characteristics (D8OE was a smog era head), better chamber, better quench. Smaller too, better cp ratio. Not "worlds better", but an improvement.

Thats an 85 model truck head, 67.5cc. A tad better than the D8, maybe. I think Ford kept using that head for a year or two, but raised the cp, the cc went to like 61cc, in 87 I think. If you are rebuilding a head, you could just buy a decent aftermarket for a buck or two more and be way more impressed. Or you could find some running E7's for dirt cheap and be done with it.

No, it won't hurt to grind the bump off. Break the corners of the machined-in pockets just below the valve. Don't take much material off, just knock the top of the edges off, easy does it. The goal is as gradual a bend as you can make it.

And ditch those smog humps! It'll take a little time to get the floor smooth, though.
