I linked the stock replacement heads bare and loaded from Promaxx. Also a link to Hughes engines for there stock replacement head. The last link is the Edelbrock head which flows a good bit more than stock.
The listed stock replacement heads did not have any flow rates listed with them.
Rumble, I'm looking for heads for my magnum, I looked at the promaxx, you said, they are a copy of the 671 head, non performance
I'm thinking you meant the promaxx 723-93605
Hey Brook. I said nothing of the sort. I looked back and can not find it so quickly. Even worse since the thread started in ‘21.
Can you post a better link. That one just keeps saying to me - dial this number?
The promaxx I linked is the Alabama guys. Nice work from them.
As far as what the head is exactly, I don’t know if it is a copy, recast, new casting, upgraded casting. Off hand, I don’t remember reading such a thing anywhere.
