If the OP is talking about an actual "flywheel" and not a flex plate you need to be careful the bolt heads don't contact the damper springs of the clutch disc like Cab said. I like the ARP bolts with a flange built in because they are easier on the flywheel. You might be able to get away with some thin hardened AN washers but double check it.

You know I'd never have a car with a flex plate!
I think I'll stick with the lube under the head, loctite on the threads and torque 'em down. Now instead of being nervous about the lack of washers I am paranoid they will cause problems.
