Head Mods: perk up your performance!
Our tried and trued head mods will perk up the performance of your engine without sacrificing reliability. Cleaner and crisper combustion gives you better snap, rev, and torque and a cooler running engine with better fuel mileage too!
Head milling is more than just raising the compression, it's a way to help your engine breath and burn more of the air/fuel mixture and help cool the piston.

The squish band is a very important part of head modifications and this is where we spend a lot of time. Just getting the proper squish band configuration without going overboard on compression will give you great results. "HORSE POWER" and "RELIABILITY"

RB Designs head modifications are set-up for premium pump gas,. and we can also set your head up to your own spec upon request.
Our head mods require you to have some good mechanical skills and basic understanding of engines. Most of our head mods require an existing squish-band clearance test so we can set your head up for optimum performance (click on the link for instructions).
Heads must be received in clean condition and coolant free. Remove any alignment pins and removable water spigots. Do not remove alloy spigots that are threaded directly into the head. 
Make sure to send at least 3 to 4 test solders with the head to be modified. (Test solder are not required for KDX 200 and 220 heads)
