I've actually been in touch with the guy that is the original marketer of the valves. Here's a link to what he is all selling on Ebay:
Looky Here is his website:
ENGNBLDR
Here's the copy of an e-mail that I got from him:
Good Evening!
Our valves are made by BBB in Argentina. This same company supplies
Qualcast, Speedpro, Milodon and many other "brands" that don't actually make
valves, but rather have valves made for them just as we do.
They are exceptional.
Darkenhancement (ebay ID) has used a couple sets, A gentleman in Florida
named Fuentes has purchased six sets, he resells them there.
The rest are private parties, (about 50 sets out there now with no
complaints) we also use these in our own machine shop in Portland.
The valve guides are American made in Nevada, the company has produced
Manganese guides for the racing market for 40 years plus. Some of the users
of Domestic guides they produce are Edelbrock, Roush Racing, and Indy
Cylinder heads, to name just a few. I do note there are some India copies
from a company called Ameera coming in now, I do not supply those.
If you are curious about me, I am 60, retired, and have been a
self-employed machinist since I was 17.
I formed the EPN company when I retired.
There are some neat old pics on our web site,

like.
As always, your complete satisfaction is gauranteed. I am aware my prices
are lower than the competition, this is because I own this line, there are
no middlemen.
Thanks,
Ted(engnbldr)
