Welcome to the site. First of all, please could you update your profile informaion, to include location and year / model of car.
As an insight into the coolant leak, here are the common possibilities (probably in this order, in my experience, but someone of the knowing variety may correct me
).
1) Heater bypass valve, located at the rear of the engine. This commonly spills coolant onto the DIS pack, killing it. To help diagnose, can you tell if you only see the leak with the heater settings on either hot or cold?
2) Split/damage to pipework in the rear of engine bay. Also risky as it's in the DIS area.
3) Coolant bridge unions at the rear of the Valley, between the two cylinder heads.
4) Thermostat to front transfer pipe O ring leaking
5) Thermostat to block seal leaking
6) Oil cooler to block plate leaking
7) Rear coolant transfer pipe to block, O ring leaking.
To be honest, if you've just had the head gaskets done, I would expect the majority of this to have been exposed and checked.
Post up your location, if you're near a friendly member they may cast an eye for you....
