Ford 429 460 275cc 95cc Aluminum Bare Cylinder Head (Pair)

Description

These performance aluminum cylinder heads are also available for the Big Block Ford enthusiasts. With bigger displacement engines becoming more common, the need for more airflow is necessary. If you are looking to build a 400-700 horsepower engine. Like the rest of our performance heads we use our "Gravity Die Cast" process. This casting process creates a much more uniform and robust cylinder head. They also offer a smaller cross section to increase the incoming air"s velocity resulting in improved drivability, power and economy.
INTAKE / EXHAUST GASKETS
Our Big Block Ford cylinder heads are designed to use Ford Cobra Jet manifolds and headers. Due to the diameter of the intake ports, you can"t use a standard Ford 460 intake manifold gasket. We recommend that you use Speedmaster PCE349.1009 intake gaskets. If you prefer Fel-Pro, use their pn#1231 gaskets.
For the exhaust side, use Fel-Pro pn# 1420. The Fel-Pro pn# 1420 is a paper gasket, but we are currently developing a re-usable copper gasket for use with modern headers. Check with one of our salesman to see when these gaskets will be available for sale.
HEAD GASKETS
These heads use the same head gaskets as an OEM Ford Cobra Jet head. Because we don"t currently make our own head gaskets for this family of engines (385 series), we recommend that you use Fel-Pro pn# 1018 on engines under 4.500" bore.
HEAD BOLTS / STUDS
As you are probably aware, the factory head bolts are 9 / 16" diameter on BBF engines. The torque value on 9 / 16" head bolts or head studs is 145lbs with high pressure moly lube. Start with 70lbs and tighten the head down in 25lb increments until you reach 145lbs.
SPARKPLUGS
Our Big Block Ford cylinder heads require the use of a 14mm thread 5 / 8" hex, .750" reach spark plugs. Below you will find a list of some plugs that fit and work with our heads:
NGK - BCPR6ES, R5671A-7, R5671A-8
Autolite - 3923, 3924, AR3933, AR3934
Champion - RC12YC, RC10YC4, RC9YC3
Remember that you need a COLDER plug when you make more power. i.e N2O, turbo and supercharging
