can you identify these heads?

[Little Al]

would like to sell them but don't know what their off of. Possibly not even HD. Got them in a milk crate with a bunch of '54 Pan parts. I thought they were possibly Ironheads?
Thanks for any help anyone can offer

They look like 900 CC ironhead heads to me.  I got two 900s and they are identical right down to the oil holes.  Could be 1000's

thanks guys!

any idea on eBay value?

Thinking I'll just put a starting bid of $10.00 and whatever I get I'll get. Thier useless to me, I only have Pans, Shovels and TC's

One Other Thing, I Believe 1000 cc Heads Had Three Different Fire Ring Diameters, There Was, Off the Top of My Head a 3.320" +/-, and 3.406" +/-, not sure about the Third???  I Could be Wrong. 

Cheers!!!
