406 headsFebruary 12 2009 at 5:11 PM

I have a 1962 406 galaxie 500 xl with matching #s that I purchased a few months back.I ordered some valve stem seals because it was losing some oil and wanted to change them to positive seals.When I took off the valve covers I noticed there were no machined spring cups.Did all 406's have spring cups or were some made without?I did compression test and all was great 170 in each cylinder with spark plugs all nice and tan.I thought that 406 had spring cups.Please help with info.Thanks much.

i had a set of 406 heads that did not have the spring cups like my 427 heads.

The 427 heads used the spring cups due the their high RPM power range. These spring cups were supposed to aid in valve spring float. The springs seats on the heads were machined for these cups also.In reality.. the "factory" rpm rating on the two engines in 1963 was actually higher on the 4-V 406 than the 4-V 427 by 200rpm and only 200 rpm's higher on the 8-V 427 than the 6-V 406...

Only the C3AE-C true 406 heads had spring cups. The C3AE-C 390 heads don't have spring cups.

The one and only set of "real" 406 C3AE-C heads I've seen had Dec '62 date codes. All the '63 date coded ones I've seen have been 390 spec w/small valves and no spring cups.
I don't believe any of the 406 C2SE heads were machined for spring cups. Would like to hear about it if I'm wrong, though!

Hi Jimmy, congrats on the new car. I'm restoring a 62XL-406 car at the moment. I've only documented 10 (hardtops)still around. Only 3 were restored, a few drivers and the rest parts cars. Is yours documented on the 1962 Galaxie registry yet? Hardtop or Convertible? I'd like to see if it's one that I'm not aware of. I don't have mine documented on the registry yet, but plan to. The C2SE-B & C heads never had spring cups. I had my C2SE-B heads machined to accept them and had them installed. By the way, it looks like Brian G-code from the forum has sold his 62XL-406 on ebay last week. Incredible frame off restoration.

Did you count my XL? Mike

Mike, I'm not sure if I've seen your car yet. Is it on the registry? Or have you posted any pics of it on here? Yes, Gene I was including yours in the count. The count is unofficial. I keep a folder specifically of pics of 62XL-406's and there are a couple that I've personally seen though don't have any pictures of. I've owned Galaxies since 1977 and probably have only seen 3 or 4 in person. The others I've found online over the years. Ironically, there seems to be more 62XL-406 Convertibles that have survived versus the Hardtops. They made less convertibles, but people were more careful to hold on to those it seems. I'll have to look to see if I have a picture of the Chestnut Hardtop. If not, I'd love to see some pics.
