insert multiple lines into a file

Hi all,

I've got some problems with editing a big configuration file .. its about 2k lines long.. anyway what I need is to place certain text to certain line number.. lets say I need to place "Something" on line 980 .. "something" else on line number 1500 and so on without tempering the rest of the configuration file ... I found somewhere this
Code:
head -981 conf.temp > conf.conf; echo "Email myemail@email.com" >> conf.conf; sed '4,$!d' <conf.temp >> conf.conf

it seems to work on one occasion but when I want to make another change in the configuration whole thing comes messed up, things appear double and so on ... any help ?

Thank you in advance ...
