MERLIN OVAL PORT

BIG BLOCK CHEVROLET

CAST IRON CYLINDER HEADS

Merlin 269cc Oval Port heads are excellent for most street-driven big blocks up to 468 c.i.d. They'll out-perform larger heads in many applications because the intake runners have a very high velocity, and the stock 2.190" diameter sized valves have been replaced with 2.300" diameter valves to also improve flow. It's the best of both worlds. True D-shaped exhaust ports help expedite the flow of spent gasses, which also contributes to improved performance. We used these heads on World's own “Daily Driver and Cruiser ”engines because of their excellent low and mid-range torque output. Merlin Oval Port heads are great for towing applications, and have a strong following in the marine market.
