About Heads

Thanks guys I would really like to run the heads I have, and have them ported to the max with a 202 valve, I. like iron heads for the nostalgic look. I've got a 1970 never used Hilborn mechanical injection set up and a out of production n.o.s. Milodon oil pan, just want to keep it vintage late 60s early 70s, thanks again for the input.........
