Trick Flow® Super 23® 175 cylinder heads deliver performance that far exceeds the power capabilities of factory heads on 283-350 c.i.d. small block Chevy engines. It starts with the small cross section Fast as Cast® runners. They promote excellent port velocity for increased low end torque and have a profile that provides excellent flow for making high RPM horsepower on small bore engines.

Trick Flow® Super 23® 175 cylinder heads have improved A356-T61 castings with 3/4" thick decks for added strength and durability. They also have a competition multi-angle valve job, angled spark plugs, and raised valve cover rails for improved rocker clearance and less potential for oil leaks.
