K-seal is your best bet there is a good chance it will do the job.

I always recommend Bar's Leaks instead of K-seal. K-seal is something like sodium metasylicate (as are most other radiator fix compounds) which is basically a very hard sharp crystalline SAND when it sets - if it gets near any bearings then they will die, it is an approved decommissioning method of engines in America, basically they shove it in the oil and run the engine, the amount of damage makes the engine uneconomical to be repaired.
I have lost a few water pumps after using it, admittedly they were old but I think their deaths were speeded up, if your headgasket lets any water into the oil then the whole engine could be written off.
While Bar's Leaks is also hard when it sets, I believe it not to have quite the same abrasive properties.
I should say this is my own hypotheses and may not be true - I just try not to risk it.

I had a leaking heater matrix a while ago, it takes ages for the carpets to dry out, I ended up stripping the seats out, squeezing out as much water as i could and putting a little heater under carpet for a few days, I replaced the matrix, it's a full dashboard out job
Replacing the heater matrix is quite a big job, although a new matrix isnt particulary expensive i replaced it in my first berlingo because i am not a fan of putting sealants in cooling systems, i had to pull the dash out completely if you decide to go down this route be prepared with plenty of patience
