you would make good TQ with the peanut ports with a small cam and heavy car with a stock stall they would work ok BUT you may have to buy two set of rotator eliminators they used rotators on both intake and ex this would be done to use a better spring i do not think the stockers will take that lift. now if you cut them heads out for a2.19 intake and 188 ex and some bowl work they would work very good
