Mikel Becks Heads

Mikel,
I do have to say that what ever you have for jets in the carb you will need to go up at least 6-8 sizes for starters, in a holley if this is what you have. The heads will require this much more just to get even for the air flow.

I've got a Holley 750HP, it has 73's all around. So I should start with 79's or 81's?
