Brodix Mopar Compatible Head - Manual (Page 2)

Dyno tests have shown that engines of
499 cu. in. or larger perform best with
35-36 degrees of timing, and 38-39 degrees
for 420-470 cu. in. engines. These tests
were conducted using MSD 7A components.
Attempts to use more timing than this could
result in damage to engine components.
Because of the high-fl ow design of the
exhaust port, porting should be limited to
radiusing the seat and matching the port
immediately below the seat to the i.d. of the
exhaust seat insert. Smoothing the remainder
of the port is acceptable, but substantial
removal of material could be
counter-productive.
Rocker stands should be mounted using the
B1 stand hardware kit. This kit includes 10
3/8 studs and 6 5/16 studs that should be
installed on rocker pads (above the intake
ports).
Nylatron rocker spacers may need to be
deburred with emery cloth or sand paper to
allow a proper fi t on the rocker shaft.
Please check these heads thoroughly in
every possible way. If you suspect a defect
is present, contact Brodix or B1 before any
work has been done.
NOTE - The use of external oil drain downs
from the heads to the oil pan is highly
recommended for better oil control and
greater performance.
It would be advisable to groove the
number 4 cam journal to provide adequate
oiling to the rocker arms.
Warning - Please be advised that heat
soaking aluminum heads above 250 degrees
Fahrenheit can drastically affect the hardness
of the head. There are cleaning techniques
being introduced into the market that utilize
high heat to remove oil, etc. from castings.
WE DO NOT RECOMMEND THE USE OF
HEAT TO CLEAN THESE HEADS.
