Title: Valve cover bolts
Post by: Peter L. on April 08, 2026, 11:41:51 AM
 Putting the finishing touches on the engine for my KR. What would be the correct style bolts for the valve covers? Tried to look at original pictures, but its much easier to just ask the experts. lol.
  Thanks guys, Pete.

The right markings but incorrect size. The NPD kit link is for a small block valve cover according to applications listed.

"RBW" would represent the head markings of the bolts. There are a number of different patterns used through the years so if your really focused then you'll want the exact pattern used for the application. Additional marking can represent the hardness rating for the bolt
