Should end in 083.
Why are you thinking about new heads? The stockers are pretty good. Anything you put on to "improve" on them is going to cost additional $'s to support them.

I've not heard that 083's are available new any longer. You're looking at used, or aftermarket replacements such a World S/R Torquers.
