IMHO no problem with brass-   as long as the thread's the same and there's 
enough material left in the internal hex drive to tighten the plug in so the 
plug goes in flush. Matter of fact, aluminum should work as well too. Both 
would be much more drillable in the smaller sizes than harder steel. Going 
too big in your spray hole simply floods the gear mesh area and might reduce 
the oil supply in that galley- which is a main lube channel for the vital 
mains & rods. The bad effects might not show up until the revs are high for a 
long time. FWIW- J Deryke
