Torque Specs

[FendleySVO]

Putting the head back on today using an 8993 head gasket. Any help on the torqe specs out there? Under search I found a spec of 90 psi is that correct..stock bolts.

3 step if I remeber right, 60,75,90.. run it couple of time and retighten them at 90

Make sure you don't have TTY bolts, if you do, you'll be snapping the heads off them at 80 ft lbs.

I actually did this myself when I did the head gasket..proper bolts and tools make all the difference..learning my lessons the hard way!! "Measure twice, drill once".. lol

Tech bulletin:

Revised Cylinder Head Gasket and
Head Bolts for 1983-92 Ford 2.3L OHC
Oil leaks and broken cylinder head bolts
may occur if the head bolts are not
properly tightened. The newest level of
cylinder head gasket and cylinder head
bolts are recommended any time cylinder
head service is performed.The new
cylinder head gasket and bolts require a
different service procedure for all 1992
and earlier 2.3L engines. If cylinder head
service is required refer to the following
procedures for cylinder head gasket
replacement and cylinder head bolt
“Torque Plus Angle” steps to provide
more uniform sealing.
The new head gasket and bolts are
uniquely different from the production
designed parts. Because of the difference,
the new cylinder head bolts are the only
bolts that can be used with the new head
gasket. If a previous head gasket is to be
used, or if head bolts are not available for
the new gasket, the previous head gasket
and bolts must be used. Failure to properly
torque the cylinder head gasket can
lead to an improper sealing surface,
which can result in a leaking condition
and broken head bolts.
• With the cylinder block and head
properly prepared, install the new head
gasket. The camshaft must be properly
positioned to ensure proper timing
alignment.
• Install all 10 head bolts into the
block, finger tight.
• Use the new “Torque Plus Angle”
procedure as follows only for new head
gasket and bolts.
• Tighten all 10 cylinder head bolts in
sequence shown in service manual to 51
ft.lbs. (70 Nm).
• Retighten all 10 head bolts in
sequence to 51 ft.lbs. (70 Nm).
• Tighten all 10 head bolts in
sequence an additional 90-100°

The previous head gasket must be used???

I'm not saying. I'm just saying ...

That struck me as odd. I think they must mean the previous style of headgasket, as opposed to the new style.

I don't know, just reporting what I'm reading.
