906 heads sufficient?

[383man]

The 906's should work fine for your combo. I ran 906's on my old eng which was a mild 440 with the MP .557 cam. I had the comp at 10.0 and it ran fine on 92 pump. It ran a best of 11.49 in my 63 Sport Fury. I ported them myself. Ron

Hi Ron, do you have more specs on that engine? Did you use templates to port the heads?
thank you for your reply
