Breathe new life into your small block Chevy with a set of FloTek aluminum cylinder heads from Speedway Motors. If you're looking for a budget-conscious, yet proven, cylinder head for bolt-on performance gains, check out these completely assembled cylinder heads from FloTek. Features like fast-burn combustion chambers, high-velocity ports, large diameter valve springs, and rugged construction make these heads the obvious performance upgrade for small block engines.
FloTek cylinder heads are designed for optimal airflow and performance on SBC engines with a 4.0" bore. Large 180cc intake runners, with an improved short-side radius, provide a rush of air into the cylinders, increasing torque. The key ingredient for big power, however, is the 64cc fast-burn combustion chambers. Air flows in and out of these chambers via a 3-angle valve job. A 62cc exhaust runner gets the spent gasses out. All told, these heads will flow 232 CFM @ .500" lift on the intake and 173 CFM @ .500" lift on the exhaust.
FloTek aluminum cylinder heads arrive packed full of standout features at an incredible value. At 20 lbs. apiece, the state-of-the-art aluminum alloy casting is a great base for any mild SBC build. FloTek cylinder heads are built with bronze valve guides, high nickel valve seats, milled and drilled ends for accessory bracket mounting, and are available in straight or angle spark plug configurations. Assembled heads add stainless valves, 1.46" diameter springs, chromoly retainers, Viton seals, pushrod guide plates, and 3/8" screw-in rocker studs - for a complete bolt-on performance package!
Maybe you are a bit more involved in your engine build - no problem! Pick up a set of bare FloTek heads, also available with straight or angled plugs, to build out with the valves, springs, and hardware of your choice.
