Heads on ebay

As far as I know the 515 casting should be identical (I got a pair as well but not been able to compare them with the 702 casting) ... someone over at tb.com said the spark plug angle where different but I don't know.
I did ask Bill Owen why the 702 castings but he did not know; as far as he told me the heads are identical to the FWD heads he initially pulled and built the very first engine with and I see no documentation that they were changed (this would have cost them money they could not spend) during the project.
So if anyone happen to have both a 702 and a 515 head and can put them next to eachother with the plugs in them and compare would be great !

I had 515 heads on my TTA motor and they work just fine. I had the 515 heads from Steve Kaminski and had them ported by Champion and they work just fine.
