ATTENTION:
VALVE SPRING WARNING FOR ALL PACKAGES
On all complete packages, it is very possible that your valve springs are not correct for your
camshaft. All valve springs should be checked for compatibility to your camshaft. Severe wear
of valve train components and severe engine damage could result from failure to do this. Check
spring requirements before heads are installed on the engine. BRODIX requires you to supply the
valve springs for any engine that has a fl at tappet camshaft with over .615 valve lift.

WARNING!
PLEASE CHECK THE HEAD THOROUGHLY
IN EVERY POSSIBLE WAY. IF YOU SUSPECT
A DEFECT, CONTACT BRODIX, INC. OR THE
DEALER IT WAS PURCHASED FROM BEFORE
ANY WORK HAS BEGUN. BRODIX WILL NOT
BE RESPONSIBLE FOR DEFECTS AFTER ANY
WORK HAS BEEN STARTED.
Inspect the head for damage from shipping, and
check valve stems for nicks by mishandling.
VALVE SPRINGS MAY NOT BE COMPATIBLE
WITH YOUR CAMSHAFT COMBINATION.
PLEASE CHECK BEFORE ENGINE ASSEMBLY.
SEVERE DAMAGE COULD OCCUR.
* Check valve to piston clearance.
* Check piston to cylinder head clearance.
Always check valve guide clearance when heads are
purchased bare. When buying the heads complete,
this is performed at BRODIX. A good cross hatch
pattern is desirable for initial oil retention.
Valve stems should be lubricated before
installation in valve guides. Recommended valve
clearance is .0015 for intake and .00175 for
exhaust.
Most bronze valve guide wear problems are
created in the initial preparation and engine
warm up. Bronze guides cannot run dry for
any amount of time.
If a valve stem seal is used, the neoprene-tefl on
insert type is desirable. We do not recommend a
tight seal.
As of January 1, 2011, all BRODIX heads
(excluding IK@, ASCS, and SUPR castings)
sold as bare castings will include the valve
bowls blended, the intake ports matched, and
a competition valve job.
Use Loc-Tite “271” sealant on rocker stud
threads. Torque to 40-45 ft-lb.
Fel-Pro or Cometic head gaskets are
recommended. Always check for gasket
overlap into chambers. New type o-ring
gaskets may imprint heads. In most cases,
they are acceptable.
Torque head bolts to 70 ft-lb in increments of
20 ft-lb. Use a drop of 30W motor oil under head
of bolt. Make sure head bolts do not bottom out
in block. Sealer should be used on head bolt
threads.
A re-torque after initial warm up is desired. Allow
engine to cool for twelve hours before re-torquing.
Check pushrod clearance with head installed
on the engine block before fi nal assembly.
Apply anti-seize on all bolts and spark plug
threads.
Alcohol cars can start with NGK-R 5671 A-10,
Gasoline (racing fuel) cars can start with
NGK-R 5671 A-9. Gasoline (pump gas) cars
can start with NGK-R 5671 A-8. This is only a
recommended starting range. You may discover
that a colder or hotter plug will work better with
your combination. Plugs must be 14mm, .750
reach. Put large fl at side of spark plug gasket
next to head.
* Race-Rite ® (RR) Series start with NGK-R
5671 A-9 for alcohol, NGK-R 5671 A-8 for
racing fuel, or NGK-R 5671 A-7 for pump gas.
Always remember big block heads have a
water passage under the intake short side.
WARNING! Please be advised that heat soaking
aluminum heads above 250° F can drastically
affect the hardness.
Cleaning techniques that utilize heat are not
recommended.
Please feel free to call, write, or email if there are
any problems or questions. We have a complete
repair service available if head damage occurs.
We also stock oversize guides and seats.
