Big Valve Head Stamp

[Tahoe]

I was wondering if anyone with a real big valve head has a picture of the "N" stamped on the boss in front of number 1?

If you can believe it, after 3 years I finally popped the valve cover and found "D" camshafts. I've been so busy having fun driving the car I never checked the cams before. Wanted to replace the gasket anyway so it was a good excuse to finally see what I have. The head is stamped as if it's a big valve, but it may not be if somebody stamped it to look that way. I was hoping someone would post a picture of just the stamped area so I can compare it mine to see if looks factory or faked.

Not willing to pull the head just to check since it runs so good, but will if I need to. This Winter is a drivetrain Winter. Install CV joints, hopefully install semi-close gears, and try and figure out what I've got inside my engine without tearing down.

This is the original head from my Sprint.

Thank You!

I think it's clear my head was stamped after the fact and is not an originally stamped big valve. It's a '68 head originally from a +2. So maybe my head was upgraded, as it were, to be a big valve. The good news is the Sprint "D" cams which makes me super happy.

I have a 1971 Plus 2S Federal model, and I think my head has just such a stamp, in front of the #1 spark plug hole. I'll try to take a snap in the morning.

Please do take a picture. My head is not 1 stamp but 3 stamps that look like an "N" It's looks to be the right size but the stampings are deeper. I'll get a picture of it and throw it in the mix.
