Product Description:
Trick Flow ® Super 23 ® 195, Fast as Cast ® Assembled Cylinder Heads for V8 SBC Pre-86, 64cc CNC 1.470" Springs. Sold Individually
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. Angled spark plugs, raised valve cover rails, and extra-thick decks and walls for porting round-out the features.
Cylinder heads are available fully assembled or as bare castings.
