Another question regarding cylinder head bolts:

- are they reusable?
- where the heck can I get new ones?

I searched a lot, but couldn't find a complete bolt set for this 287 engine.

All bolts have a 1/2-13 thread. The long ones with 4" and 4-5/8" length seem to be normal grade 8 bolts (reagarding the sign on the head of the old bolts), but the short ones with 2-1/2" length have a "M" on the head - whatever that means...

Any hints on the head bolts?
