    ok so im going to replace my head gasket on my 2001 Acura EL, AKA Honda Civic. The Haynes manual lists the following head bolt torque specs for this car
    1.7L engines
    Step 1.....168 in-lbs
    Step 2.....36 ft-lbs
    Step 3.....49 ft-lbs
    1.8L engine
    Step 1.....29 ft-lbs
    Step 2.....Tighten an additional 90-degrees
    Step 3.....Tighten an additional 90-degrees
    New bolts.Tighten an additional 60 degrees
    These torque specs are for SOHC engines.

    From what I can tell it looks like the 1.8 SOHC engine uses TTY bolts while the 1.7 SOHC engine uses non TTY bolts
    From this I would say you can NOT resuse the 1.8 TTY bolts but you could reuse the regular 1.7 bolts.

    When reusing any head bolts it is important to use a tap and clean the threads in the head and a die and clean the threads on the bolts and oil the bolts before installing using a NON click type torque wrench, instead use a good quality beam or dial type and follow the manufacturer torque specs. If any binding is felt while torquing a head bolt, remove it and start again, possibly even cleaning the threads again.

    As a rule is the manufacturer lists a final torque spec numerical value for a head bolt then it is not TTY and can be reused, if the manufacturer lists an initial torque numerical value followed by some additional degrees of turning then these are definitely TTY and should not be reused.
    I have a 1.7L SOHC in mine and will be reusing my original head bolts after they are cleaned up and oiled.

    Just my 2 cents
