EMPI Hi-Performance Dual Port Cylinder Head — 85.5mm Bore, Stainless Valves, 3-Angle Valve Job (98-1373-B)

Stock heads work, but when you want stainless valves and stronger valvetrain without going full race, this is the upgrade. EMPI's Hi-Performance dual-port head (98-1373-B) starts with the proven 98-1355-B 85.5mm casting and adds stainless steel Manley valves, hi-rev springs, chromoly retainers, bronze guides, and a 3-angle performance valve job. SCORE-approved, sold each.
