I used Autometer electric gauges, and both senders are 1/8-NPT.
For oil pressure, I drilled and tapped the cover near the oilfilter (see the sticky, https://ls1tech.com/forums/showpost....49&postcount=5).
For water temp, I pulled the plug out of the right head. You can buy an 1/8-NPT to M12x1.5 adapter (sticky again, https://ls1tech.com/forums/showpost....4&postcount=55). I had an 1/8-NPT female to 1/4-NPT male adapter that came with my oil pressure gauge and noticed that it was really close to M12x1.5 but slightly larger. I clamped it in a vise and ran an M12x1.5 die down it. I doped it up with ARP teflon thread sealant and it hasn't leaked yet.
