Designed for hydraulic roller camshafts. Exhaust port is raised 0.500 in. over stock. Requires a custom-built header.
Trick Flow’s Twisted Wedge® Race 206 heads feature fully CNC-profiled Twisted Wedge combustion chambers and valve arrangement with port-to-valve seat blending (bowl blending), plus .500" raised exhaust runners and raised valve cover rails. Fast As Cast® runners deliver near-CNC-ported airflow and power for about the same price as cast heads.
Twisted Wedge Race heads have additional material for porting, thick decks and chamber walls for durability, intake port shaping for Fel-Pro #1262 gaskets, stud mounts for roller rocker arms, and huge valve spring pockets. They are available fully assembled or as bare castings. Sold individually.
