These fittings screw into the heads and then a compression fitting on each hose attaches to them. HD only calls
for an o-ring on each fitting. I replaced the o-rings, but also added a layer of teflon tape to the fittings.
The o-rings get oiled lightly to keep them from distorting as the fittings are torqued down.
|Installing the Oil Fitting
And then the compression fittings on each braided oil line are tightened onto the fittings in the heads. Spec
is 13-17 ft-lbs.
As you can see in the above picture, in order to be able to position the intake manifold
against the heads, the cooling oil feed lines to the heads should be installed after the heads are torqued and the throttle
body is bolted in place.
Now on to install the Rocker Arms and their covers.
