Right eventually got the job finished as ive been doing it in between work n stuff and as richard youll said the water pipe at the back of the head was different BUT the original pipe off the endura head could'nt be fitted to the new (second hand) head as the thread sizes were different, anyway the pipe mated up to it ok. The only other differance was the metal plate behind the camshaft pulley etc because the head i got was later found out to be off an earlier car and did'nt have power steering or air con so this had to be changed also but apart from that all's well and its purring like a kitten, Well knocking it's head off like a normal diesel does LOL

Thanks for the help guys much appreciated nice one!
