    The perfect bolt for those tight manifolds.

    After searching for days for narrow-headed exhaust manifold bolts, I found these at a great price. I needed to replace bolts that used the large head/stack of washers technology. These worked perfectly and already had an oily finish on them, so they installed with ease. Plus, with the star heads, there was no slipping.

    Best header bolts on the market

    If your like me your tired of tightening your headers every 1000 miles these bolts and lock washers are for you the extra thread engagement and really nice heavy duty lock washers will keep your header tight one small note is to go ahead and plan on chasing/cleaning and blowing out your threads on your heads with compressed air or the bolts will most likely not thread all the way in.
