What piston be this ?

A few weeks back I posted about an intake manifold that didn't align to both head's mating surfaces (327), asking for reasons why this may be. Well I went ahead and threw caution to the wind, pulled the heads and am very glad I did. I'll spare you all the sordid details of the "rebuild" that supposedly took place, suffice to say that I'm planning for new heads now and someone in North Florida needs to have their tools taken away.
So wrt new heads, I want to pick the proper combustion chamber size as per my pistons so as to have a streetable compression ratio. Which brings me to my question:

The tops of my pistons are stamped "L2166N" as well as ".060" My questions is can anyone identify the manufacturer and spec of these pistons by the L2166N stamping ?

Thanks in advance ~

I have the same pistons in my 327 except they're .040 oversize. I had 461 double hump heads (64CC)on it and it would clatter with 93 octane pump gas. I added 5 gallons on 100Low Lead Avation gas to each tank of fuel for awhile. This took care of the clatter problem, but I got tired of driving to the airport for fuel and eventually switched the heads out for Edlebrock aluminum heads with 70CC chambers. This has cured my clatter problem on straight 93 octane gas, but I wonder now if just changing to 64CC aluminum heads might have been enough.

Those are factory replacements for the 350/365/375 hosre 327's from vettes and chevelles, and a few lucky deuces.
