need help identifying some Gen3 heads

[GPXSS]

best i can tell, i have 2 diff P/N on some heads
24503769 - i got a pair
10218179 - only have 1... im thinking its the larger valve 3400 head

anywhoo, I can't remember what the ports look like on each of them that lets you determine what years they are.. Ill take pics of the fronts tonight.

BTW Shaun, these are the heads I have that we talked about. I also have the 3400 plenum (sorry.. its not a 3100) and valve covers with new felpro gaskets.

quick way to tell:

3400 the gasket hole for the center alignment tab or "tit" is on the wrong side compared to the 3100 IIRC.

one is to the left of the center port on is on the right of the center port.

just checked those numbers in our parts department, neither number is any good.

The 10****** number should actually be an older head, ie a 94-95 head, and then the other set looks to be a 96-99 3100 set. That's just comparing to the head numbers we have listed...
