You are purchasing a single cylinder head part number TFS-51410010-M61 for a Small Block Ford. This head was run on my engine dyno for literally two pulls. This head is unmolested and unmodified since it left the doors at Trick Flow. I had a pair of these. The other head was picked up by the customer and this head was left at my shop. The head is current as it was ordered new a few motnths ago. A matching head could be ordered through Summit Racing for $600.00.
The customer ended up going with the street version of this head.
