I talked to the vendor I bought the heads from and they said they use that stamping on all their blocks and heads to verify its a piece they sold for warranty reasons..Case closed! lol

that's not what the description said,and yes 243's came on some 4.8's and 5.3's,look it up
If they came from LS2s or LS6s they are called 243s, if they came from other engines they are called 799s.

5.3s did come with 243s. End of story. You're incorrect.
Indeed. A good friend of mine owns a completely stock 2012 silverado and his 5.3 has 243 clearly stamped on both heads.
Correct! i have a 09 gmc with the 5.3 and it has 243 heads!
