XAT RACING WORLD FIRST EXCLUSIVE!! As it turns out, there's not an off the shelf answer for aftermarket valve guides for these engines. So, of course, we partnered up with an experienced manufacturer to custom make these!
If you have the heads off of your engine for any reason, it would be worth checking to see if it needs servicing, and chances are, it might.
Price is for a full set for 1 engine!
