An essential for any engine builder! Valve Guide Drivers make short work of changing out those worn guides in those swap meet panheads you bought for a song.

When working on heads, everything else is based off of the valve guide geometry. These drivers will help you be sure your new guides are put in correctly, which you definitlely want, since the seat geometry is based off of the orientation of the guide.

These drivers are constructed from a high-quality steel alloy that will put up with years and years of use.
