Hi Sterling, its not that hard, have a go yourself
Take your time, get everything tested and machined by a decent shop, buy all new stuff, and bolt it together slowly but surely making sure it all absolutely clean
Dont skimp to save a few bucks, if in doubt machine it or replace it
I have a block you are welcome to for free but it needs to be bored +.060" , you would probably be better starting with a complete motor. There must be a few 2 lt cortinas still around at the wreckers ?
People will help you and you will end up with a very solid rebuilt motor
