Carl:
Do you have the product number easily available for the ARP head studs for the A engine?

2 ea AP5.750-ISB
Depending on your head, these may be a quarter inch too long. If they are, just order shorter ones or use a really thick SAE washer under the nut. The length is in the part #.
No need to tell them you are buying these for a Model A, they've never heard of one.

I think you better recheck that second part number.
I can re-check my invoice from them as well as measure what I have on my engine.
The sizes I listed are 1/32" longer than what is in Snyder's catalog:
Regular short studs: 3-15/32". Long outlet studs: 5-23/32".
I did re-check my invoice from ARP, and the sizes listed are what I have.
