[Steve C.]

"First, a word about factory Pontiac heads in general: Pontiac heads were originally designed to get heavy cars up and moving. As such, they emphasize low-end torque over top-end power. Pontiac port volumes are roughly equivalent to a 350 Chevy small-block, yet most Pontiac engines are at least 50 ci larger. When it comes to porting the factory Pontiac heads, H-O Enterprises' Ken Crocie, a recognized Pontiac expert, says "You can't make a Pontiac head big enough. You can make it wrong, but not too big."
