Um wtf? If you're referring to the DOD holes you just use standard plastic plugs for the holes in non DOD configuration.

No need to drill and tap them the corvette valley cover seals them.

so does the the LS2 valley plate although blocking off these hole offer added protection from the pressurized oil that could possibly leak from them. ucntzme went ahead and took W2W's advice and blocked his holes

where these holes are located? and what they will cause if they don't get blocked?

the valley cover actually blocks the holes with o-rings so high pressured oil doesnt leak out since the ls1 guys swapping to an ls2 dont use the DOD(displacement on demand) but for high boost or big nitrous applications uczntzme has decided to block his.
