KRE's second War Chief series water jacketed cast cylinder head designed strickly to be for higher end performance engines. This head
has raised and enlarged intake runners and enlarged exhaust runners with an exit at stock round port location. We stood up the valve angles from the stock 14 degree
to 10 degree's to help with high valve lift flow and decreased combustion chamber volume. Extra cooling holes have been added to the center of the head
to help cooling and water flow to the center exhaust ports. Valve centerlines has been spaced to accept
a 2.300 and 1.800 valve size combo. As cast intake flow comes in just under 400 cfm out of the box. Requires rocker shafts and .180 offset
intake lifters.
