Max 4.155" bore. 4.166" bore gaskets can be used on 400 race engines with up to 4.155" max bore with minimal chamfer. When using aluminum heads, we recommend gaskets with soft copper wire rings (such as 344-1010). This ensures that the aluminum head is not "scarred" by the combustion seal. Shim style 344-1094 will also work well with aluminum heads. Multi-layer steel gaskets offer current leading-edge technology and provide a long-term, leakproof seal called Perma Torque MLS Flo-Tek 102505 Assembled S/B Chevy Aluminum Heads (more details) 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 or plugs, to build out with the valves, springs, and hardware of your choice. Application This Part Fits These fully assembled heads are ready to run and are a great match to flat tappet camshafts. They're compatible with solid (mechanical) flat tappet or hydraulic flat tappet cams with up to .550” lift. The valve springs (single with flat wire inner damper) have a seat pressure of 120 lbs. Valves are +.100" long and must be used in conjunction with aftermarket aluminum roller rocker arms to clear valve springs used which are 1.46" diameter. The valve springs have 120 lbs. @ 1.800" installed height and 290 lbs. of open pressure at 1.20” (coil bind is at 1.160”). Charts (JPEG) (GIF) Installation Tips Stock stamped steel rocker arms will not clear 1.437” diameter valve springs on these heads. Must use aftermarket roller tip or full roller rocker arms if using large diameter springs. We recommend or . Heads feature valve cover rails that are raised 3/8” so you can use roller rockers with short valve covers (note - some factory A/C brackets may have interference issues). Rocker arm studs should be torqued to 45 ft.-lbs. Exhaust ports are square and work with style gaskets. Champion 271RC12YC spark plugs (14mm thread, 5/8" hex, flat gasket seat, .750" reach) are what we recommend as a starting point. This is a straight plug head (not angled plug). Ignition timing should be between 35 to 38 degrees total. Set the timing with the vacuum advance hose disconnected and rev the engine up until the mechanical advance is fully in, then set it at 35 degrees to start with. You can experiment with more timing later to see if the engine runs better at closer to 38 degrees, but we don't recommend exceeding 38 degrees on most applications. Heads are not drilled for steam holes that are required on SBC 400 engines. Torque head bolts to 50-65-80 ft.-lbs., with 75 ft.lbs. torque on the bottom. Use Permatex 80631 style sealant on the threads.
