First off sorry for starting another thread about this. I want to get this right the first time.

This motor looks similar to mine, just half the cylinders.

Here's my set up. It looks like I should aim for around the etching, but center it as best I can? So 11/32 drill bit with heavy grease on it and mark the bit down 1/2 inch so I don't go too far. The pipe taps I'm seeing are a 27 thread, is this the correct one to use? After I get that sorted I think that I'm good to go.

Checked that one out and got most of the information I needed. Just wondering if anyone has done it on my engine or a similar v-4 and if they have any advice or 0ictures.
