Customer Reviews


great product! bolts right up! Comes with everything you need except new head bolts. The bolts you see attach your rocker boxes to the new heads replaceing the studs & nuts on stock heads, and are a nice improvment. I had to place a 2nd order to get new bolts but the good people at J&P gave me a break on the express shipping due to the misunderstanding THANK YOU! I recommed getting new bolts and like the 12pt colony head bolts that J&P sells


These heads are awesome. As with any S&S product I have purchased in the past,they bolt right on and have superior quality. The only thing you have to do extra is rejet your carb due to the increased air flow.
