LT1 or LT4 Heads?
I purchased some heads off of ebay a while back and the heading was LT1 Heads. But when i got them, i could swear they are LT4 heads. They have the bigger studs and the port work looks similar to the LT4 heads. I just had my brother tell me the #'s on the heads and was wondering if anyone can help me figure this out. I don't have any detailed pictures of them though. This is the #'s and the location of them.
2033 in black marker
4060 on the inside
10128374 inside where the valves are
08543 on one end
08743A on the other end.
Any idea what all these #'s mean?
Any help would be very appreciated.

I Compared my heads against some heads taken off of a 92 LT1 and it had the same casting #, my stud's and guideplates were completely different though. So i figure mine are LT1 heads (i looked under the oil cap on my dad's 96 lT4) and sure enough, LT4 was stamped on it.
