The Ultimate Bolt-On Cylinder Heads for SB-Chevy

These heads feature 3/4" decks (great for nitrous or blower applications) and exceptional flow characteristics (ideal operating range: 2500 to 6500 RPM; higher ranges possible depending on combination of parts). Standard valve spacing and 23º valve angles make them the perfect street cylinder head for 350 to 383 engines. Sold individually.
