You need 5/16-24 for the original stud .

You sure about that?  IIRC, at least on mine, I *thought* that the bolt hole in the head for the stud is coarse thread, and you use that itched stud for the regular valve covers.  If you had the t-bird dress up covers you had to get different studs that were coarse on one end (to go into the head) and fine pitch on the other for the dress-up nuts specific to those covers? Is my recollection wrong on that?  cars still tucked in for the winter else id go check!

Here are the dimensions for the rocker studs for the stock metal valve covers:

5/16”-18 X 5/16”-24 X 3.86”

 

For the aluminum T-Bird covers the dimensions are:

5/16”-18 X 5/16”-24 X 4.125”

 

Coarse thread at the heads and fine threads for the valve cover nuts.

when I changed over to the alum T-Bird covers I used 5/16-18 grade 8 all-thread, cut it to the length needed. That way the coarse thread gives you more options for acorn nuts wing nuts etc.  I did it mostly because I had a hard time finding anyone who stocked the correct T-Bird studs.

Thanks for the replies. I found a nice set of enlarged aluminum acorn nuts at restoration shop her in the Netherlands. I am still looking for the wing nut style if anyone finds some. Let me know. I will post pictures of my engine build in the very near future.

Here’s an ebay link to some cast wing nuts you can drill and tap for what ever size you’d like.  Pricing is not all that bad either.

For those of you still looking, I bought some from both sources. The link I noted in an earlier post (with picture) cost me $40 shipped for 2 bags of 4, Eelco brand packaging.

 

I contacted the seller in Ted's link above and got a bulk pack of 8 for $16/shipped. The Ebay seller that Ted listed sells the rough casting, and it isn't tapped for threads, but has a 1/4" hole if I recall correctly. That would be best for a Y-block fella's purpose.
