Technical Specs
 
The smallest intake volume runners in our line-up, but donÍt let size fool you. Our 305cc ñAs Castî with CNC bowl blend or fully CNC ported 315cc aluminum cylinder heads will provide you with flow numbers most medium sized heads, and some larger, can only dream about. This line was designed to optimize low and mid-lift airflow, while still generating impressive peak figures. Their application should be focused on smaller cubic inch Big Blocks (396-502), with a primary operating range of 2500-6800 rpmÍs (this range is an average and will vary with engine displacement as well as component selection). These heads should also be given strong consideration in larger street driven or marine applications up to 555 CID, where low rpm power and drivability are a factor. The 315 version is extremely versatile with its incredibly strong low and midlift airflow figures as well as peak numbers approaching the 400 CFM mark. Either one of these two cylinder heads would be a great choice if your looking for big torque, strong low rpm performance, and still have good rpm capabilities. Both the 305cc and the 315cc come standard with AFRÍs trademark .750î thick head deck, reinforced rocker stud bosses, and are equipped with premium one piece stainless steel 2.250î intake valves and 1.880î exhaust valves. Standard combustion chamber volume is 119 ccÍs on the 305 ñAs Castî pieces, while our fully CNC ported 315cc version comes with a 121cc chamber. Both are available with an optional 114cc combustion chamber as well. Chevrolet Big Block - 315cc Competition Package Ported Heads, Bare - 121cc Combustion Chambers
