AFR is proud to reintroduce our Slinger Speedway Limited Late Model engine approved cylinder head. This cylinder head features a 100% CNC ported intake, exhaust and combustion chambers, 5 angle AFR valve job, A356 aluminum castings and high-quality components throughout. The AFR/Slinger Cylinder Head will shave roughly 38lbs from the front nose of your vehicle. This cylinder head must maintain all original manufacturer's specifications. No alterations of any manner permitted. All competitors must pre-register the AFR heads with Slinger Speedway tech officials. Minimum combustion chamber 62cc, maximum 2.08” intake and 1.6” exhaust valves both with minimum stem diameter of 5/16”. Valve spring retainers are the only titanium parts allowed.
