Chevrolet Vortec Small Block Cast Iron Cylinder Heads

Since 1996 we have been working with the Chevy Vortec cylinder heads. We know and have the right casting number heads to make the most power for your application.

Note to Serious Racers:  All Chevrolet Vortec heads are not created equal. Don’t give up horsepower by running the wrong Vortec head!

Yes, the older ‘906 and early Canada ‘062 Vortec heads are a solid 10 horsepower better than the currently available “Mexican” castings found on the ‘602 crate motor and as the over-the-counter replacement head. .


The older the Vortec head is the better it will run on your race car.  We have been modifying and porting Vortec heads since they were introduced in the mid 1990's. We have the correct casting number heads to help put you in the winners circle.

The Chevy Vortec head is an excellent choice for a variety of race applications. Just make sure you spend your hard-earned money wisely by getting the best flowing Vortec heads available.  If you are serious about running up-front, we have an excellent supply of ‘906 and early Canada ‘062 Vortec cores that will give you a winning horsepower advantage over the '062 Mexican castings. The ‘906 & early Canada ‘062 Vortec heads work especially well on limited valve lift applications. The bottom line is this:  Running the early Canada ‘062 or ‘906 castings will give you a huge horsepower advantage.

Cast Iron Intake Manifolds for the Vortec Heads

To use a conventional bolt pattern, passenger car cast iron intake manifold on Vortec heads, the intake pattern on the Vortec head must be changed. This is our labor operation #410-AX. Good News! We have performance, high-rise cast iron intakes in 2 and 4 barrel that will bolt on to the Vortec head. Our #201V-M is a performance, cast iron 2 barrel intake. Our part #401V-M is a perfomance 4 barrel intake. See our Vortec Intakes. Link to Intake Manifold FAQ's.
