452 heads

Gear ratio is 4.10 3500 stall and 28" tires. I was holding out for alum heads. Then I seen these. one reason I wanted the alum was the flow. I can see if I can get full flow specs fromt he guy. For the price he is asking its worth a chance. Short of having them checked and lapping the valves I was hoping to put these on and have it fit inline with my combo. Wanting a nice lumpy hot street car. With good power.
