Trickflow Super 23 Cylinder Head, SB Chevy, 195cc Intake, CNC Ported 72cc Chambers - .540" Hydraulic Flat Tappet Springs

Trick Flow Super 23® 195 cylinder heads for small block Chevy are a direct fit, high performance replacement for factory heads and accept most original accessories. Ideal for 302- 406 c.i.d. engines, these heads feature high-velocity, small cross-section intake runners to promote low-rpm torque and high-rpm horsepower. Fast As Cast® runners deliver near-CNC-ported flow and performance for about the same price as regular cast heads. Modern CNC-profiled chambers promote combustion efficiency, helping maximize power with less ignition timing and reduced potential for detonation.

Improved A356-T61 castings now feature 3/4" thick decks for additional strength and durability, improved 3/8" pushrod clearance, and CNC profiled intake port entry. 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.

Note: This head is 50-state legal CARB EO# D-747-1. Sold individually add 2 to cart for a pair.
