BBM FE Cylinder Heads

—BBM FE Cylinder Heads

Bear Block Motors (BBM) is proud to introduce the incredible new BBM FE cylinder head for 390, 427, and 428 big-blocks with 2.150/1.650 or 2.200/1.650 inch intake/exhaust valves with the lightweight 11/32 inch stems. Combustion chambers are engineered for optimum swirl and quench right out of box. High-swirl/high-quench chambers allow for more aggressive ignition timing on today’s more unforgiving pump gas. BBM heads flow 35-50 more CFM than current aftermarket FE head and 3 to 5 degrees less timing requires. Also available are CNC-ported FE aluminum heads with 2.250/1.710-inch valves, which calls for 4.230 inch minimum bore size.

BBM FE cylinder head features include:

• Precision high quality castings

• Machine quality control second-to-none resulting in a precision fit with performance to match

• Factory installed Time serts utilizing the highest quality, strongest-threaded insert available on all rocker system and exhaust manifold mounting holes, as well as the front/rear accessory mounting holes

• Manganese bronze valve guides are factory installed

• Hardened high grade ductile iron valve seats installed and interlocked

• Approximate 75 cc heart shaped combustion chambers

• Intake runner vol. 180cc

• Exhaust runner vol. 130cc

• Heads will fit standard 390 bore with 2.200/1.650
