Summit Racing™ precision cast cylinder heads are made from tough A-356 aluminum alloy and feature Permanent Mold "As-Cast" technology. Port accuracy is unrivaled--meaning CNC porting is not required to provide superior flow. The result is CNC-ported performance at a fraction of the price! We start with precision CNC-finished faces and bolt holes for accuracy and fitment. American craftsmen expertly size and install the manganese bronze valve guides and interlocking ductile iron seats before finishing with a competition-grade valve job. From there, the decks are given a final pass for superior finish. They are finish-assembled in the USA with top-quality components like PAC Racing springs, fasteners, one-piece 21 4N stainless valves, machined locks, Viton® seals and chromoly steel retainers. The final result is the performance you want and Summit Racing™ quality you TRUST!

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. Modern CNC-profiled chambers promote combustion efficiency to maximize power with less ignition timing, reducing the potential for detonation. The result is more power and torque, better drivability, and greater throttle response from your street performance engine. The features don't end there. 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. Heads are available assembled with premium components including stainless steel valves, bronze guides, 7° machined locks, chromoly retainers, and your choice of PAC Racing valve springs for flat tappet or 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.

FLOTEK's 290cc big block Chevy cylinder heads with 112cc combustion chambers are recommended for moderate street or street/strip BBCs with displacements up to 509 cu. in. operating at or below 6,500 rpm. It may be necessary to check clearance and slightly modify some domed aftermarket pistons due to the efficient heart-shaped combustion chamber on these heads (most of the newer designed dome profiles will clear). FLOTEK recommends removing material from the piston and not the cylinder head, as the combustion chamber shapes are very critical to flow—altering the cylinder head can unfavorably affect flow and power performance. FLOTEK's medium-sized 290cc oval port cylinder heads are designed for 3/8 in. pushrods with 0.120 in. wall thickness. They're available assembled or bare for a variety of engine applications. NOTE: This item is not sold as a pair; this is a single cylinder head.
