Bowtie Vortec Heads

I am a huge fan of these heads and where we can use it. If you have a flat tappet or flattop piston rule where a cast iron head is needed, this is the head for you. We like it in 2 Barrel & 4 Barrel applications. If the cubic inch is bigger than 362, our CNC porting program makes this head viscous. We give you multiple options on what you can do with this head. You will not go wrong as long as it is being used in the correct application.
