Here is some info messaged to me from member: rszmjt
Who raced in Div.6 and worked in a speed shop back when these heads came out. He still races today and is flying! 7.50’s @ 180mph. With a small block and a 5 gear Lenco.
That’s got to be a fun ride Mike!

FWIW - Your heads are “Superflow” heads , the fireballs we’re a street version with way less preparation , and weren’t released till about 1975? fireballs were just rough ported and had no polishing or blending in ports and under valve seats. They were also stamped “fireball”
Reason I believe this is I worked at a local speed shop in Calgary Ab in 1972/73 and I ordered a set of “Superflow” small block heads which I ran for years on my S/G Vega . We also sold at least 8-10 sets of “Fireball” heads which were way less $ so local street racers could afford them. “Superflow” heads were the Cadillac of Crane heads and way more $$$$.
Those heads are yours are Awesome shape and IMO worth every $ your asking.
Cheers. Mike
