Doing a new set of alum. heads on our blown small block pro street car.What kind of valves do you guys think will hold up the best. Not a drag car, just a street car.Any help would help me make a decession on the valves.Thanks JOHN SR

Manly Severe duty Intakes valves and Extreme duty exhaust valves.
The equivavlent in Ferrea valves will work fine as well.

I agree, just make sure you get carb(s) dialed in and don't run lean....
