Big Block Chevy Merlin III Cast Iron Rectangular-Port Cylinder Heads
Improved Performance Over Chevy's Legendary LS6 Heads!
Merlin 269cc Oval Port heads are excellent for most street-driven big-blocks up to 468ci. They'll out-perform larger heads in many applications. When larger engines (454 to 540ci) require added flow, choose the Merlin Rectangle Port cylinder heads. With RightCast 320cc and 345cc intake runners, you can expect solid gains in air/fuel mixture combustion charges. These World Products heads will really respond to higher compression ratios, and are ideally suited for hot street/strip cars.Technical Specifications
