any idea about this head

[1969510]

Ok so I have this head it's an open chamber with a cam thats stamped 210 there is no stamp on the head to tell what head it is I.E. w53,a87,u67. It appears to be shaved... all there is a number stamped on it in a normaly blank place going vertical on the spark plug side of the head it reads 3083. on the rear of the head it is stamped no-5 3-6-75

That was my first thought too. The valves look a little big for a 210 head. Hmmmmm...

210 =

 

"This is the head that came stock on the 510. Tiny 1.125" intake ports, square exhaust ports. 1.50" intake valves and 1.30" exhaust valves. There have been variations reported on the valve sizes. This head is believed to be originally designed for the L-13, an engine never imported to the U.S. . These heads are usually avoided on performance applications."
