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.

• Precision high quality castings

Some flat lifter cams will be compatible with these specs, however, proper requirements and break-in are

the responsibility of the end-user.

For milder flat tappet application we also offer a single spring with damper

110 lbs, seat pressure with 285 lbs @ .500 lift, max lift of .550 inch. This package  comes with 10 degree steel retainers,

If using solid or hydraulic flat tappet lifters, consult the cam manufacturer of your chosen camshaft to insure

these specs are suitable for your use.

Please discuss with your professional engine builder for your application needs.
