AFR SBC 180 Street Heads, Eliminator LT1 / LT4 Reverse Cool

AFR Eliminator Series SBC 180's! PN: 0908 , 908

AFR's All new port design, all new chamber design, new casting design and updated valvetrain! The new AFR 195 race ready head outflows the previous comeptition version head (Roughly 285 cfm out of the box!) Casting improvements include improved oil drainback, heavier duty castings and better material control. Revised valve, 8mm LS1 technology, and matching springs, retainers and locks are all standard on the new AFR Eliminator line. These lightweight components will allow a more reactive, higher rpm and more reliability. When comparing the new and old AFR style valve train the valves alone yield a 23g weight savings. This weight difference will allow higher rpm potential and will allow the springs greater control before valve float. The new 1.260" spring package allows a 40 gram weight reduction vs. the older 1.550" spring option, yet allows for the same spring pressure. When comparing the new and old valvetrain a single cylinder utilizes a 126g reduction in weight where it matters most - on the valve side of the assembly. Consider this icing on the cake with improved flow characteristics, and an improved casting on the already industry leading AFR cylinder heads.
