No all of the old heads, phased out and are now replaced witht he ones you see today. I think those must be VERY old because i have never heard of them. Are they rotors or sprays. The heights also changed with the heads, and if you need replacement my suggestion is .....
Rotors - Tbird (lower pressure)
Hunter PGP (higher Pressure)
Sprays - Toro 570
All obtainable at Sprinkler Warehouse, You can move to a higher pop up using funny pipe which is like an extension cord, to the regular line, so you dont have to dig down the actual line
