What would be a good intake/cam to get maximum use out of these heads

Asked by: jskunar11
That all depends on your goals. The intake and cam that may be recommend for a regularly driven street car are not the same intake and cam that we might recommend for a drag car or something that will be used in other forms of racing. Please give us a call Toll Free: 1-800-888-6473 and someone in our sales staff can discuss with you your goals and point you in the right direction.
