Repairing cylinderhead old school way. Did not want to spend the $600 on valve lapping, cleaning, decking, General refurbishment of head. Head was warped so I decked it myself. ( YES I know the head could / should have been heat cycled to straightened.)
Question:
What is the bare minimum of the Head thickness?
.
( from valve cover sealing face to head gasket sealing face.... no gaskets included.)
I'm checking next to see how close the valve to piston clearance is.
Minimum is 5.280”.
That is the reason I'm checking . It's 5.270" after decking
Time for a new head, or cut it more and buy a .020 shim. Junk yard head may be the way to go.
Going for the double gasket. Will report back sporadically to let everyone know how it went .
I checked the piston to valve clearance by assembly of head , timing belt, and clay on piston. Intake valve will have .07in clearance.
Wish me luck.
Going with 2 MLS FEL PRO GASKETS.
Have put 1000 miles on engine now and no problems. Broke in around country roads and suburbs 0-35-50 sporadic speeds and rpms (not high). Then 45-55 on interstate, then bumped up to 50-65 for hour long drive .
The 8th day went 55- 80 mph for about 1hr
9th day tried hard take offs and 70- 80 for and hour or more . Now just driving normal to work under 70mph normal , not hard throttle .
Getting 33 mph. Back and forth to work.(suburbs and interstate)
I agree with you, thanks for your sharing.

( not related to double gasket )
Gas milage has gone down because I swapped to 15" rims and larger tires. 205/55/15.
Also not going easy on throttle anymore. Average is 28 mpg . Still staying under 80mph and 5000-5500 rpms
