Brodix 18° Pro Stock style cylinder heads and intake (Big dukes) brand new. I bought these heads and never completed the project so now I’m selling them. These heads are ready to bolt on complete with springs, valve retainers etc. They are direct from Brodik ready to go. These heads and intake are special order and most places are out of them. I can ship but prefer local pickup. The heads and intake are as cast and the intakes ports are 456cc runners and are rectangular port. The valve angle is 18 degree and makes big time power. These heads are nitrous friendly. Also comes with Brodik part # PM 1800 intake which is also as cast. The intake top is for a dominator type carburetor. The PB 1801 were the original designs in this legendary series. The part number is: PB 1802 is a cast ported version of the PB 1800 capable of flowing over 480 cfm intake and well over 300 cfm on exhaust. The professionals at BRODIX have contoured each intake port, exhaust port, and combustion chamber to flow its maximum potential out of the box.
