Mikael, it's not specific to supercharged engines but road racers and other 
long-haul engine users often add "sprinkler systems" to the rocker covers. 
This is a pressurized oil line that attaches to each stock rocker cover with 
a bulkhead fitting, with a piece of hard line soldered inside, that has 
'appropriate sized' drillings just above each rocker arm. Silver State runners 
use them with iron heads with about the same cooling results as aluminum 
heads. LOTS of friction from ball-pivot rockers. As Julian said, Inconel 
exhaust valves s should be in there regardless, if its a blown boat engine. 
Cheers- JDeryke
