Trickflow Super 23® Cylinder Heads, Sb Chevy, 215cc Intake, 72cc Chambers, 420lb, Chromoly

Trick Flow Super 23® 215 cylinder heads will give a huge performance boost to race-prepped small block Chevy engines. Based on the proven Super 23 head design, the Trick Flow Super 23 215 heads feature enlarged valve springs to help pull in more air and fuel with higher lift cams. The larger Fast As Cast® runner design provides near-CNC-ported airflow and power for about the same price as most cast heads. The result is more airflow in the mid and upper rpm range—and that means more power. Other features include angled spark plugs, extra-thick decks and walls for porting, and raised valve cover rails. Trick Flow Super 23 215 heads are available fully assembled or as bare castings. Sold individually.
