Honda B Series Cylinder Head Modifications
Pictures of our basic cylinder head work.

This head has also been prepped for use on a larger than stock bore application. It also incorporates our CNC'd chamber quench pads.

Basic Rework includes complete combustion chamber shaping/finishing, as well as port bowl/short-turn porting. Intake and exhaust port entries and exits are also matched.

We begin with a stock (new) B16 head casting and perform our own version of the ITR modifications for an 18+HP improvement.



Our legal rework includes mini combustion chambers, precise non-cosmetic bowl shaping, and of course our famous valve seat configurations.

We've designed a compact combustion chamber and high velocity ports for these 1.6 liter engines running limited carburetion.

Note that when stock valve guides net the proper clearances, we carefully shape them for additional airflow.


These heads are available with a variety of intake and exhaust valve sizes to suit specific performance applications.
