Arguably the most dominate cylinder head in motorcycle drag racing, this completely redesigned casting eliminates the limitations of the original Vortex (formerly MTC) cylinder head casting. The previous version, in Pro-Stock form, used 47mm intake and 39mm exhaust valves. After it was CNC ported to optimize air flow, it flowed about 160 cfm. The Vortex II flows as much air without porting. It flows 160cfm with guides and a valve job with the ports AS CAST!

Getting more air flow from smaller valves means smaller valve pockets in your pistons which will give you more compression and a more efficient combustion chamber. The all new Vortex II cylinder head represents the latest technology in cylinder head design and will be the standard by which all others are compared for years to come. Designed and manufactured by WARD PERFORMANCE.
