The bolts are the same as Chevy small block V-8 stick flywheel.20 bucks buys race quality stuff from your local speedshop or places like Summit or Jegs online.The SBC bolt may or may not come with serrated lock washers.Do not rely on suspect bolts for a flywheel.
You can throw away the stock sheetmetal locks if you want.Red Loctite works better,just make sure you clean the threaded holes in the crank carefully.It also seals the threaded hole so engine oil won't seep past the bolts.
