Re: Vortec 114 ?
I've been researching this a lot lately.... There seem to be two different versions of these heads and I'm not entirely clear on the differences yet.
There is a 114, and a 113.
It appears that the two different version pertained to 1998-03 and then 2000 to 2005, and they overlapped.
These may be marine heads. the 98-03 version used 5/16 rocker studs, the 2000 to 2005 used 8mm.
The Volvo I/O setups (marine) may be responsible for the difference. I found a pic of a 113 in a boat with non adjustable rollers, with a type of rocker girdle (very weird).
There are pics on my photobucket page of each (link in my sig). The valves are different between the two but that is probably just a remnant from the rebuild process.
The difference may be in hardened seats, but I'm not sure. Somewhere in those numbers stamped on the heads may also be the port volume on the intake runners... I'm still trying to run that one down.

Re: Vortec 114 ?
I just bought one head, 114 casting form Odessa cylinder heads, I told them i wanted 113 casting but they sent 114 instead.
According to them, GM makes same castings with diffrent numbers 113, 114. This seams strange to me.
Looking at the heads side to side, they do look the same.
I just wanted to know if they flow the same?? Having one head 113 the other 114 casting makes me wonder!
