Performance Stage 1 Ported/Polished Cylinder Heads, Pair

Ported cylinder heads will always produce better torque and horsepower than heads that are "as cast".  For any motor, these are a terrific upgrade over stock.  Valves are 40mm x 35.5mm.   The round ports on the Stage 1 heads produce great torque and low-end power.  They're great for small displacement motors with mild to mid-range cams, terrific for buses and heavy vehicles, and will work much better than stock heads for larger displacement engines.
