Brodix Mopar Compatible Head - Manual

Installation
Instructions
Check piston to head clearance.
Check valve stems for burrs created by
number stamps or mishandling.
Check valve to piston clearance. It will be
necessary to machine valve reliefs on pistons
with stock valve locations.
Bronze guides should be wet-honed for
clearance. A good cross-hatch pattern is
desirable for initial oil retention.
Valve stems should be lubricated with cam
lube or a lubricant which will stay in the guide
until the engine is warm and suffi cient engine
lubricant is oiling the valve and guides.
Recommended valve clearances: .0015 Intake
and .00175 Exhaust. Use an oil and STP
mixture for lubrication of valve guides.
Most bronze valve guide wear problems
are created in the initial preparation
and engine warm-up. Bronze guides
ABSOLUTELY cannot be run dry, even
for a second. If a valve stem is used, the
neoprene-tefl on insert type is desirable.
A tight seal is not recommended.
Torque head to 75 ft-lb using increments of
no more than 20 ft-lb. Care should be taken
to check the length of the top row of head
studs. It may be necessary to shorten these
studs to avoid interference with rocker arms.
A re-torque of heads after initial warm-up is
desirable, preferably after engine is allowed
to cool completely.
Heads have a 68 cc combustion chamber
out of the box. They may be fl at milled as
much as .130 in. at a rate of .0057 in. per cc.
The intake correction rate is .010 in. per .010
in. removed from the deck.
Check pushrod clearance with the head
installed on the engine block that will be used.
Use Anti-Seize compound on all bolts and
spark plug threads.
Champion ‘C’ Series spark plugs are
recommended. Gasoline cars can start with a
C 59YC. This is only a recommended starting
range. You may discover that a colder
or hotter plug will work better with your
combination.
Put large fl at side of spark plug gasket
next to head.
