85. Locate the factory water choke outlet at the left rear
corner of the cylinder head. When cars are converted to
a manual choke, this outlet is sometimes removed. If
yours is missing, you will need a Moss #470-245 water
choke outlet because engine coolant must flow past the
ECT in order for it to work properly.
86. Remove the clamp (30.1) securing the choke coolant
hose to the water choke outlet. Pull the hose off the
tube. You may want to take a moment and clean the
area around the choke tube before you start the next
step.
87. Remove the two nuts (31.1) securing the water choke
outlet to head using a 7/16" combination wrench.
Remove and set the water choke outlet aside with the
nuts. They will be re- installed after we fit the engine
coolant temperature sensor (ECT).

88. Remove the two studs (32.1) from the head. It will be
necessary to double nut the studs or use a pair of vice
grips to break them loose. (Fig 33, 34) Discard them;
they will be replaced with longer studs supplied in the kit.
If the studs are very hard to move, try soaking them in
penetrating oil for 30 minutes before you try and remove
them.
89. Clean the surface of the head thoroughly, removing any
gasket material or sealant. Use a gasket scraper or a
single edged razor blade. (Fig 35) Take care not to
gouge the surface, which may cause a leak later. It may
be easier to remove the gasket and gasket residue if you
spray it with brake cleaner and let it sit for awhile.
90. When you are done, the surface should be clean and
free of any debris that might prevent a good seal. (Fig
36)
If you took your safety goggles off, put them back on before
to do this step!
91. Spray brake cleaner into the holes for the studs while
holding a rag over the hole and the nozzle of the can to
catch the splash back.
