When something to be drilled off a press is that critical, I measure the 
exact distance the drill needs to go and wrap tape around the drill bit at 
that point so that I have a guide. Better would be a stop on the drill bit 
but not everyone has a stop.

Keep in mind that there is nothing to leak in the hole, the device just 
needs to be tight enough not to unscrew itself (and if it did, It would 
just land in the shroud).

BTW there is an interesting figure in the SAE reports (which naturally I 
have misplaced) that related to the temperature at various points on the 
head with the spark plug near the coolest point and the thermocouple near 
the warmest.
