THANX! for that info craig.

Like I said, there are so many years and designs that it is hard to focus on fifties tech.

Thanks I will check the engine casting number, it will give me some clues. I don’t have the engine or ****** out so can’t check the crank or caps.
...

If you lift the car and remove the lower bellhousing inspection cover, then turn the engine over with a remote start switch (and have a good work light) the dot on the crank flange can usually be seen.
I've been told it's easier on a manual transmission car than with an automatic, but fairly possible.

I had my heads done when I lived in New Jersey by a friend
in a raceshop.
When I moved down here to Alabama I encountered several people who were car collectors, and they had a million questions about the engine rebuilding that I had just completed.
The valves were one of the topics. They hammered me for weeks about not putting in the hardened valve seats etc. It got so bad that I went to a local machine shop run by by a bunch of oldtimers.
I explained what I wanted to do,and requested a price for the work and the cost of the part required to do the job.
The fellow who was dealing with me pulled his glasses down to the tip of his nose and asked me "how old are you?" I told him,I was in my sixties. He asked if I was going to drive the car on weekends shows etc.i said yes.
He told me to just drive the damn car,the valves will out last you,than turned and walked away.
That was the end of the valve controversy.

I’ll add that without the hardened seats, valve guide wear increases significantly which ends up just costing more in the long run. If it’s a vehicle that’s just being driven 2500 miles a year or less, then the cost of hardened seats my not be justified depending upon your budget. 70K miles on unleaded fuel without hardened seats seems to be the record here with 35-40K miles being the average where the heads must be pulled again and worked on. At that point, most customers simply opt to go with the hardened seats and never look at the inside of their engines again.
