i highly recommend the "aircraft performance requirements manual" by r.v.davies. you will require uk cap385 along with it since it is extensively used in conjunction with the text. (already mentioned by 80/20)
specific boeing type related perf manuals are also great - from the 747-200/300 era and probably other types of similar vintage.
if you combine the above three it's a pretty unbeatable combination.
be prepared though for a fair amount of mental gymnastics till you start getting the flow, unless you have the benefit of some "chalk and talk" in a classroom. do not worry if you find the text 'dry', you will be atleast the second person to find it so.
