I bought these heads on ebay,
I checked the chamber size and they are at too small for my application. I used a plastic syringe to check them and came out with an average of 68cc's.
The decks are true. I measured the deck using Scotty's method on his site and came out with .077-.079. If the stock deck was .110 -.105 then you can see why the chambers are the size they are. From the information I could find, these heads were 75.8 cc from the factory.
The seller is going to refund my money because the listing stated they are stock and not milled. Turns out his machine shop did not let him know they had been.
They are stock in the ports and chambers though so they could be ported.
If my pistons were not out of the hole so far I would be using them.
I looked up the prices on the parts used to build them and it came out to around 550.00 plus the cost of the valve job. He shipped them to me for free and would like to save the money to have them shipped back so I agreed to list them here for him.
Call him if you are interested.
