nope, just tq em down to 25 ft lbs.

do clean the threaded holes out good. make sure they are oil free, brake cleaner and some Q tips works well. this way the bolts are tq'ed properly.

you can put a dab of grease on the top of the push rods and a smear on the valve spring stem too. keeps you from having a bone dry start up. just a little bit of grease, you dont need a whole lot.
