SOURCE: Head bolt torque specs needed for 96 tbird 3.8

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

  1. 20 Nm (15 lb-ft).
  1. 40 Nm (30 lb-ft).
  1. 50 Nm (37 lb-ft)
Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:
  • Tighten to 40-50 Nm (30-37 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Short Bolts:
  • Tighten to 20-30 Nm (15-22 lb-ft).
  • Rotate an additional 175-185 degrees.
  • Go to next bolt in sequence.
Here is a pic of the sequence

SOURCE: tightening head

New Headbolts are recommended

Long bolts are torqued to 46'lbs + 90 degrees.

Short bolts are torqued 43'lbs + 90 degrees.

Start in the center, and work to the edges, torquing the bolts in two stages.

Rockers are torqued to 22'lbs.

SOURCE: Head bolt torque specs?

I really really really hope you turned the bolts an additional 90 degrees after torquing to 22 Ft-lbs. Otherwise, you may be taking that head off again.

Best of luck,

David

What is the cylinder head tighten torque


Have a look on this link. You may be able to find your car:

SPECIFICATION LOOKUPS

Cylinder head bolts are usually tightened to around 65 ft-lbs, depending on what the car is.

There's more than 4 cylinder head bolts... There's usually 10 bolts.
There's also a sequence for tightening the bolts:

cylinder head tightening order Google Search

When tightening cylinder head bolts do it in 'stages' and follow the sequence .. ie.. tighten the bolts finger tight first, then torque them up to about 25 ft-lbs. Wait 2 minutes.

Then tighten them to about 45 ft-lbs in sequence. Wait 2 minutes.

Do it again up to about 55 ft-lbs. Wait 2 minutes.

Tighten them up to 65 ft-lbs or whatever is recommended for your car.

Tightening in order/sequence pulls the cylinder head evenly onto the block. Waiting 2 minutes between stages allows a 'stretched' bolt to 'settle'.
