No fuel injection. Just want to add auxiliary gauges for more info.

I think these two spots (circled in yellow) are what I’ve heard may be options. Is this the oil pressure location by the distributor? The other spot on the intake is one I think I’ve read someone drilled and tapped for coolant temp. I was hoping to not have to go that far. Are there any other options? I think I also read that one could tee for the oil but that the coolant temp had to be a direct sensor into the liquid. Is this true?
Thanks all.
