Basically I want to know if it matters which way the coolant flows through the heater matrix?

I have a disco 300 with a 200 engine in it, I recently had the headgasket go so had it all sorted with skimmed head and all, however noticed the other day that I had coolant on the starter again. I guessed the hg had gone again so took it back and he said it could be the heater matrix pipes so I've got some new ones.

The problem is that if I put them on the way they came off they seem too long and too short, so basically does it matter?
