No templates. I measured carefully, scribed in some sharpie ink, then used a drill to do most of the work. Not sure what others use. Then cleaned it up with a dremel.

I never did bridgeports before. I was nervous too. But it's good to expand your skills sometimes. Always better if it turns out well.

Now I'm kinda nervous about my next engine. Gotta BP the intermediate plate because I have to use a reverse runner manifold in the application due to a lack of space. I already ported this engine to 74 spec so I'm not sure if I'll run the carb out of flow. I do have a Holley 600 to use if necessary, but I'd rather stay with the stock hitachi because it ran wonderfully in this car before. I also have a 390 holley but it is set up to use an open plenum so that won't work on a half BP.

There is basically a very real chance this half BP 13B won't work out as well as the 12A did. But if I think about that, it probably will turn out not as well. So I should concentrate on the positive like I did while doing the 12A and things will work out fine.
