lots of good stuff here, thank you.

as mentioned it was a conversation with the Holley tech dept that lead me to ask here. I completely respect the limitations a tech line has to operate by.

Looking at Bob's installation I ordered a 45 degree bung which will be a better candidate to weld in then the supplied clamp on boss Holley provided. Summit has it listed as steel, not stainless, fine either way.

I'll keep an eye on the sensor degrading. The pictures Ed posted was interesting. With the ring land opened up like that I am surprised the ring had much of any sealing ability and didn't take out the bore.

As for making a stainless steel block I guess I'm not really seeing the advantage over welding a bung in the same spot. I'd like to understand the square shaped port if you could give more detail.
