There are no completely resistant varieties; all peaches are susceptible.
Frost and Redhaven cultivars are less susceptible.  Choosing a resistant
variety is very helpful, but is not a guarantee.  
When looking for resistance, look for resistance to your most troublesome
diseases.  Sometimes there's a trade-off; varieties don't necessarily have
multiple resistance.

My only experience with a curl resistant variety has been with the 
Frost peach, which, it is claimed, will become more resistant as the 
tree gets older.  Mine is in its second bearing year but still exhibits 
curl.  I sprayed with copper (specifically COCS) earlier this spring  
but apparently not early enough.  Widely available, this is just one

Raintree offers it, too.
