Edelbrock Big Victor 3 Pro-Port 11 degree cylinder heads are designed for high rpm, large displacement big block Chevrolet race engines. These heads are a unique departure from current spread port designs using instead the familiar Pro Stock style symmetrical port layout. These heads are semi-finished in that all machining on the valve axes has been omitted to allow custom designs with unique valve angles and positions. They are supplied with no combustion chamber and small ports to permit various port and chamber finishing options. All are also treated to a Hot Isostatic Pressing (HIP) process prior to heat treat and final machining. This process greatly improves metal density and tensile strength thus significantly extending their useable life.
