Can I tap a head for an ac bracket on my 71/SBC 350?

[BigTopGT]

So, I'm in south Florida and it's starting to get warm. Since. I don't want to sweat half to death this summer, I'm looking to get the AC working again and have a Sanden compressor on hand.

The only issue is I need to get the bracket sorted out and it looks like I'm missing a bolt hole in the head that'd make a bracket work.

Can I tap the head shallow and run a bolt with some locktite to keep her in place? (Pic attached if approximately where I'd need the hole tapped)

Seriously not wanting to hit a water jacket.

Thanks in advance for the advice, fellas!
