RHS Vortec Cast Iron Heads

The RHS Vortec heads are an excellent performance and endurance improvement to the Chevy production Vortec cast iron cylinder heads.

RHS did a nice job with this replacement Vortec heads. Not only does it flow more than the Chevy production Vortec, it is also a much stronger castings. The tall, narrow Vortec style intake runner is superior to the standard style Chevy intake port.

RHS Vortec heads produce great throttle response and low to mid-range torque for Street Stock type circle track applications. Features include Vortec style intake manifold flange, thick deck surface for increased durability, machined valve cover area, hardened exhaust seats & are machined for screw-in studs.

“UnderCover Ported” RHS Vortec Head

The Vortec style chamber is superior to standard Chevy chambers on "double hump" style heads. 

Stock RHS Vortec heads flow 225 cfm intake and 145 cfm exhaust. With our "UnderCover Porting" the flow numbers increase 10 to 20 cfm on intake and exhaust. We offer disguise packages to make the RHS Vortec head look more like a production Chevy Vortec casting.
