Headbolts
 

Why do some flathead headbolts have an H on the head, and some have an S on the top? (These are Canadian Flatheads)

I've come across both, on various engines.

Likely identifies Fords sources.

Really?
No one has a definitive answer as to why headbolts can have either an 'S' or an 'H' on the head?

My trust in the Fordbarn as the ultimate pool of old timer knowledge is deeply shaken...

The most likely answer was given. Bolts supplied to Ford from alternative suppliers. Not definitive, but most likely. There shouldn't be any physical difference between them. It's not like Using one type over another is an ancient speed secret.

Re: Headbolts
 

At the time there were two different suppliers for the bolts.
One was located in Hamilton Ontario and the other in Stratford Ontario.
Thus the H and S

Clearly the humour intended in my post didn't translate well to text.
I'll try harder next time. :)

You gotta remember, old men, don't usually get nicer as time rolls by :)

Always keep in mind that old age and treachery, beat youth and skill ;)

I used to be young, I know about it!

I did assume your reply was tongue in cheek. A winky smily emoticon would have helped.
