These heads should be legal, they have been setting on my shelf, in the shop, for 25 years, and are untouched. The casting # is 2780599
They are just a "stock" set of heads, with valves (no rocker arms).
I had these to build an engine with, but I bought a complete engine, so I don't need these right now. I have pictures to send if you e-mail me
morgandd1@yahoo.com or call me at 618 978-8426 cell or 937 770-1357 home
Thanks Class Racer
