plug wire separator bolt holes

[Big RED Burban]

Hey yall I like the way the plug wire separators are set up on the tbi engines and I noticed that there are shallow holes on the outside of the heads that the separator brackets are bolted into I was wondering if you can drill these holes into older perimeter bolt heads without hitting water thanks

I wouldn't risk it. Better to get the separators that attach at the valve cover bolts than to try to drill the heads.

Yea don't risk it do a search there are a ton of different plug wire separators out there you would be surprised at what you find. You may find something that will work for what your trying to do with out a giant headache.
