The one and only set of ProMaxx heads I’ve ever touched

I called and talked to him after I inspected these heads and what he said was these heads come across the ocean like every other offshore head. But he said they come in as raw as they can be ordered then the do the seat, guide, valve job, etc. he offered me some deal pricing but at the time I wasn’t doing customer work and prices that I received would have raised my customers cost. The valves jobs were beautiful compared to other Edelbrock and Edelbrock style of heads.
Their heads are really good they are probably not on the level of your best heads or rod bloomer heads but there is a guy down here with Pro Max CNC heads on his 368 cubic inch small block mopar and I swear that thing must make 600 horsepower it runs 6 40 in a 1969 Dodge Dart custom.
