Quick Overview

Honda K20/K24 (CRV K24A1, Type S K20A2, Type R K20A, RBC, RSP) The NEW Pro 156v2 CNC cylinder head is the ultimate cylinder head for your street car. The original Pro 156 raised the bar and set the standard for entry level street cylinder heads by offering the highest quality in the industry and airflow that surpassed many very expensive race heads. The newest version of this head takes it a step further with improved airflow throughout the entire lift range, top to bottom. We spent countless hours balancing airflow to make sure this port is the best on the market. This head offers 360 CFM on a stock size valve, giving you plenty of flexibility to run a wide range of VTC and simplifying installation for those that don't find themselves pulling the engine out of their car to degree cams and check clearances. You can install the head and enjoy the power.
