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"
