For the flywheel bolts I would recommend using 1/2" bolts and Stage8 Chrysler 440/Hemi locking flywheel bolts. They are only available directly from Stage8. You can also use ARP Pontiac flywheel bolts. If you are going with 7/16" bolts, any good quality Chev V motor bolts work.
I have used both 153 and 168 tooth flywheels on 292s. The 153 was needed for a Chevy II. In both cases used a small block mini-starter with straight bolts without issue.
