Default Darkening original engine bolts...

I searched the Forum earlier today, looking for info about recreating the blackish, "Raven" finish on original engine bolts.

Let me say that I am NOT building a "points car", but would like to come close to correct appearance.

I saw some comments about cleaning the bolts ( de-grease, wire-brush ), heating with a torch, then dunking in used motor-oil.

Can someone suggest a temperature to heat the bolts to if I were to heat the bolts in a pan, say in the oven or gas-grille (don't tell my wife!) ?

It would be a lot more expedient ( and controlled ) to heat a batch of bolts in a controlled manner than for me to do one at time in a flame...

Thanks !
