AFR SBC 180cc Street Heads

AFR Eliminator Series SBC 180's!

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 275 cfm @ .600 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.

The Small Port, High Velocity Torque Monster

 

The AFR Emissions Legal (versions from 1969-94 with heat riser, CARB EO #D-250-2), 180cc intake port small block Chevy cylinder heads are available in your choice of straight, or L98 angle plug versions. These heads feature a 75cc or 65cc combustion chamber with a 64cc exhaust port and a 3/4” thick head deck (ideal for nitrous or blower applications.) The 65cc chambers are designed for flat top or dished pistons; domed pistons will require additional machining. Standard valves are 2.020 intake and 1.600 exhaust with AFR’s hardened ductile iron interlocking valve seats. The exceptional flow characteristics, ideal operating range of idle to 5500 rpm (higher rpm ranges possible depending on combination of parts) This exciting new product mimic’s the GM L98 heads dimensionally and is a direct bolt on. The only exception is the exhaust port is raised .100 to increase performance. It also is available in a straight plug version with the plug location patterned after the GM Vortec head. The head comes with both center bolt and perimeter bolt valve cover patterns. They come with 2.020 - 1.600 8mm valves, #1256 Felpro intake port opening.
