These cylinder heads feature a 65cc or 75cc combustion chamber with a 64cc exhaust port and a 3/4'' thick head deck (ideal for nitrous or blower applications).

The exceptional flow characteristics, ideal operating range of 2000 rpm to 6500rpm, 23° valve angle, and standard valve spacing make this the perfect street head for 350-400ci engines from 1955-1986.
