My 306 has the "crossover" pipe that goes from cylinder head to cylinder head. My question is: Should I block them off ? Right now they are head to head, but the valve on the passenger side is "blocked" off. The car is not really a street car, mostly weekend racer. If it's "blocked" off is it really serving any function ?
