AFR - Airflow Research

Airflow Research heads have been on some of the fastest cars in history. Several big names in drag racing ran CNC ported AFR aluminum heads on their cars including: Bob Glidden, Warren Johnson and Frank Iaconio. NASCAR drivers used AFR to port their heads. Needless to say, AFR - Airflow Research knows how to make a cylinder head flow its best. In their early years, AFR was a head porting and polishing shop. They also consulted with GM on small block Chevrolet 350 engine heads. Then in the 90's, AFR began to manufacture their own line of aluminum heads. Then when the LS1 came out, they were at the forefront again by making a Gen 3 LS1 aftermarket cylinder head.
