This is my first post here,been kind of lurking around and reading a lot of good info while i got all my ducks in a row. Ordered my gauges from USDiesel, (Isspro) but the instructions are a little sparse. On my old truck, a 6.5 chevy, the Banks downpipe had a bung, but I want to put the thermocouple in the exhaust manifold on my dodge. My question is, where is the best place to drill the hole?

Grease your drill bit and drill slowly. Grease your tap and tap slowly. Use a magnet to get out any shavings that are in there or a small vaccum.
