Installing Headers

Special Note:

We suggest leaving the

headers in their plastic bag during the initial fit.
If the headers do not fit your application, you
can return them within 30 days of the purchase
date for credit of the purchase price only. The
returned parts must be in new condition (no
scratches, dents or dings). Chassisworks
reserves the right to return to the customer any
header kit that is returned in substandard
condition.

There are many manufactures of cylinder heads and several of them have made changes to the basic
dimensions of the stock head. These changes will affect how our headers fit because we have built
our headers to a close tolerance. Below are suggestions of modifications that can be made during
your installation to insure the best fit.

1.  Bolt hole resizing of the header flanges.
2.  Different spark plugs to gain clearance for spark plug wires.
3.  Different spark plug boots or wires to clear the header tubes.
4.  Shimming the transmission mount up or down for additional tube clearance to the frame. If the

transmission has been relocated from the stock location or replaced with a different model, the
header fit may be affected.

5.  Minor dimpling or denting of the header tubes.
6.  Minor grinding of the header flange around the head bolts.
7.  Changing the cylinder head fastener style for more clearance ( i.e. 12 point bolts or nuts, no

washer or head studs).

8. The shape of the exhaust port may require a gasket change or modification for best seal.
9. Not all cylinder head manufactures use the same specifications on the width, height, and angle of

the exhaust ports. If the ports are changed from the stock location in any way, the headers will be
too wide to fit between the frame rails.

10. It is a good idea to test fit the headers on the engine prior to installing them. Make changes

before you have the headers in the car.

We suggest angle plug heads for better
fit. The spark plug clearance will be
very tight on the straight plug heads. A
shorter length spark plug is available
from most vendors. Champion C63YC
is a good starting point for a street s
block with straight plugs. Howev
even this spark plug will come very
close to some tubes. MSD makes a
heat shield material that should be
wrapped around the tubes that have
spark plug boot interference.
