Our Pocket Port-R focuses on what matter most. Valve job, blending and gains in the bowl area, and the combustion chambers to allow a bit more knock protection specifically on pump gas. The results are phenomenal, particularly when paired with conical spring kit, with some Ti Retainers and locks, magic hands, and custom valves. Now that’s a set of spec heads even your mother could love, and live reliably while you hammer away on them.
