Trick Flow® Super 23® 175 Cylinder Heads for Small Block Chevrolet
Trick Flow® Super 23® 175 cylinder heads vastly outperform factory small block Chevy heads on 283-350 c.i.d. engines. They feature small cross section, Fast as Cast® runners for excellent port velocity to promote low-end torque and a profile that delivers outstanding flow for making ample high RPM horsepower on small bore engines. Modern CNC-profiled chambers promote combustion efficiency. That helps maximize power with less ignition timing and reduces the potential for detonation. It all adds up to more power, better drivability, and greater throttle response on street performance engines.
Improved A356-T61 castings now feature 3/4" thick decks for additional strength and durability. Other features include a competition multi-angle valve job, angled spark plugs, and raised valve cover rails for improved rocker arm clearance and less potential for oil leaks. Assembled cylinder heads have premium components including stainless steel valves, bronze valve guides, 7° machined locks, and chromoly retainers. Several PAC Racing valve spring options are available for flat tappet and hydraulic roller cams.
Trick Flow® Super 23® 175 heads accept most original accessories. They are emissions-legal under CARB E.O. #D-747-1 for 1995 and earlier GM vehicles with Chevy 262–350 engines.
Cylinder heads are available fully assembled or as bare castings. Sold individually.
