Keep it simple chaps !

Go to any electronics second-hand shop and you can pick-up heat sink for 
next to nothing.  This can be used in multiple sites - filter resistors, 
spark gap, etc.

See my spark-gap and other bits:

Even after long runs the spark-gap is only just perceptibly warm.  The 
filter resistors on the other hand get HOT and some heat-sink is essential 
IMHO.
