Chevy Double Hump Fuelie Heads

 The “double hump” or “fuelie” heads have been around since the 1960’s. They are still used in a variety of applications. We have a good supply of used ‘186 & ‘492 heads available with everything from “Undercover Porting” to CNC Sportsman Porting.

Stock “double hump” heads flow 202 cfm intake and 141 cfm on the exhaust. If you must maintain a stock looking port, consider our “Undercover Porting”. With our “Undercover Ported” they will flow 220-230 cfm intake and 165 cfm exhaust. This flow improvement will add 15 to 25 horsepower to your engine.
