Can anyone decipher these head casting numbers? I bought these on Ebay, and noticed they're a tiny bit different than the ones I've seen before...( not the port design, but the casting spots (no, NOT flash)seem a little different...
HEAD 1:
Looking at the exhaust port side of the heads:
Top Left=0007209511629855
Top Right=0072K5332856
Bottom, below 3rd ex. port=6 82 2 04 41 C (0?)3 0
Looking down on valvetrain, ex. valves towards you:
Bottom left corner=853
HEAD 2:
Same 853 as above,
Top Left=9928112570729855
Top Right=9282U2780856
I've looked up "LS! casting #'s on Google, but all the numbers that come up are different than the ones on these...
I know they're 5.7's, since they both have "5.7" in the casting...
Thanks <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Re: Can anyone decipher these head casting numbers? They are 853s. Used from 99-mid 00. In mid 00, they switch suppliers and also changed the casting numbers. They are all interchangable, and no performance differences. I think the other number is 241.

So just to be sure, I am fine to P&P these for a 2001, right?
