Thanks. This is not my first rebuild mostly v8 a couple 4 cylinders.
The head is torqued down. I cleaned both sides mating surfaces with acetone couple times.
Used the documented torque procedure. This was the first time using torque angle Gauge it was not too hard.
I used a two-foot breaker bar that helped make it easy.

This car has an interesting torque procedure.



DOHC head torqueing procedure
Initial dry bolt torque in sequence to 48ft-lb following the torqueing pattern in stages to 20ft-lb, 30ft-lb, and final 48ft-lb. This establishes the proper clamp load on the gasket.
This is followed by removal in about 1/4 turn in sequence until loose.
Bolts washers, threads and bolt heads are oiled with clean engine oil and reinstalled finger tight.
Torqued in sequence to 22 ft-lb then 37ft-lb and then additional 90-degree turn.
The 90 degrees is important so do not guess at the 90 degrees. You can eyeball it and use a 1/2 drive breaker bar and make the 90 degrees turn in a single smooth motion.
If this is not followed the new gasket will end up leaking.
Torquing sequence
intake side
8-4-1-5-9
7-3-2-6-10
exhaust side

Timing chain set installed. One more step done.
