The Engine Quest Vortec heads are an excellent performance and endurance improvement to the Chevy production Vortec cast iron cylinder heads.
The Vortec style chamber is superior to standard Chevy chambers on “double hump” style heads.
Straight plug design. Standard valve size is 1.94 x 1.50. Can be machined for larger valves.
Stock Engine Quest Vortec heads flow 222 cfm intake and 145 cfm exhaust. With our “UnderCover Porting” the flow numbers increase to 245 cfm intake and 175 cfm on the exhaust. We also offer a disguise package to make this Vortec head look more like a production Chevy Vortec casting.
We may even be able to make the Engine Quest Vortec head look like the production Chevy Vortec head.
