C5/Z06/C6 AFR 205cc LS1 Mongoose Street Head

For the ultimate street LS1/LS6 aluminum cylinder head AFRs all new 205cc emission legal head are your only choice. Specifically designed for 1995 to present Gen-3 Chevy Corvettes, Camaros, and trucks. AFRs LS1 head offers unmatched flow performance (300 CFM at .600lift) and features 2.020 intake and 1.600 exhaust valves with AFRs iron ductile interlocking valve seats. With only 205cc port volume (same as stock LS1 head) this is an incredibly 70 CFM increase over stock casting creating unbelievable port velocity and performance. The 205cc is ideal for normally aspirated 346C.I. to 396C.I. These heads come with 66cc combustion chambers. AFRs LS1 is a direct bolt on, no special parts required. Structural features like Air Flow Researchs trademark 3/4? thick head deck, a must for blown and nitrous applications, reinforced rocker stud bosses, and thick wall runners provide unparalleled durability. An exclusive new modern combustion chamber design with double quench pad area helps the LS1 generate huge low and mid lift airflow numbers. If you need a snake charmer for that pesky neighborhood Cobra Mustang? look no further. (These heads are producing over 470 HP to the tire with a MILD 224 street cam, 114 LSA.), CAM Not Included.
