Head Bolt missing

One of the reasons for starting on the restore of my 8N was a missing head bolt. Someone had been there before me and broken it off. I finally got the remains out after a week of fiddling with it.

So where do I get a replacement? What grade, etc.?

It was in the corner next to the #4 cylinder, which had half the compression of the other 3 - hoping this solves that problem.

Sam,
I replaced all of mine when I rebuilt my '41. Picked them up (grade 8) at the local bolt shop for 50 cents each. Just make sure to get the two different lenghts.

I figured the 60 year old ones had done their job. I would also recommend a new head gasket if you replace them and pull the head just for fun (grin)!

I wouldn't use a grade eight bolt in cast iron like a block. There are uses for hard bolts but this isn't one of them. Won't stretch like a grade five so your torque is going to be off and if something is going to strip I would lots rather it were the bolt. Worth two cents?
