Race-ready AFR 220cc SBC Eliminator racing heads feature 100 percent CNC-ported intakes with greater detail. They also come with 100 percent CNC-ported combustion chambers and 80cc exhaust ports with a 3/4 in. thick head deck (ideal for nitrous or blower applications). Valves are lightweight 2.100 in. intakes and 1.600 in. exhausts with AFR's hardened ductile iron interlocking valve seats. The 1.550 valve springs installed are for use on solid roller camshafts. The valve springs are setup for up to .710 lift. The heads have 7/16 rockers studs, adjustable pushrod guide plates installed.
The heads have 5 passes on them and are just like brand new. I had them bolted to an older motor and spun a bearing on the 5th pass.
These cylinder heads are competition-ported by AFR.
