Never mind

I have taken measurements. I have done the math. We will mock it up if the .020 bore works with this block.
That ^^^^ is great news. It’s the only way to know for sure. And when someone comes in here in a year and asks the same question you did, you’ll tell them exactly what all of us have told you. Mock it up and measure, then modify to fit. There are a lot of competent guys here, some have commented on this thread and given you good responses, and those responses were predicated by all the junk we’ve screwed together that didn’t work like the manufacturer said, or the book said, or someone else said, would work.
