I am looking for 8 original valve cover bolts for my 400 GM engine. They have a 5/16 -18 thread. 5/8 length. They are 5/16 hex flange head with a D in the center.
Any assistance would be greatly appreciated. |

I have both. The cupped ones are for the valve covers. Flat ones are for the oil pan. I also have Es in both styles.

Valve cover bolts
Thanks to all who responded. I located a set valve cover bolts. I'm not sure but I believe the cupped bolts were used before 1969 and the flat head bolts were used from '69 to 1981.
