I just received a set of F3TZ-6051-A. NOS from eBay. They do look like OLD stock. The fire rings seem pressed onto the gasket, but loosely; no bond. I don’t know if that matters.

The package wasn’t sealed, so I’m not even sure if these are the legit IDIT gaskets or not. The seller does have a few more sets if anyone’s interested.
Edit- one of the numbers stamped on the gaskets (1816689C1) matches a different part number. So if the two numbers Wes posted are the only legit IDIT gaskets, these ain’t them
Edit #2- the seller got back with me and has 3 unopened f3tz-6051-A sets. He checked the gaskets in those packs and they all have the same 1816689C1 number stamped on them. So, I dunno. I’ll hopefully get a chance to measure the fire ring tonight to see whether these have the NA or turbo ring.
Edit #3- put the micrometer to the set from eBay as well as a pair of Victor Reinz gaskets. Both fire rings are about 0.1”.
So, unless I’m doing something wrong, which is more likely than not, gaskets with 1816689C1 stamped on them are NOT IDIT’s, but they may be sold in original packaging labeled as IDIT.
Wes, is there a number printed on your IDIT gasket?
and Wes, thanks for bringing up the issue with drilling these. To be honest, I thought the hole you drilled looked pretty good; until I looked at the one you did with the punch. Very clean. And I like the P-pump backdrop
