340 to 372 stroker kit

Because your geometry will never be correct if you don't do something about it. Ever.

It's actually B3 racing engines that makes a kit to do the correction. IIRC, with the same rocker, .620 gross lift and stem height about .050 higher I needed a .240 up and .060 back correction.

That's a bunch. But my sweep is about .045ish IIRC.

Forget about getting the sweep centered. Get the sweep as narrow as you can.

EDIT: my post only applies if you are using econo W2 heads. If you have the stands milled and have offset shafts and blocks than ignore what I posted.

As stated originally I’m a rookie when it comes to building/restoring cars. So I’m not sure why you gave me a dislike for asking for clarification and info to bring to my father and the engine builder. I would like to learn when we aren’t doing things properly so I can bring facts to them to justify change.
But my heads are the 55cc race heads so I assume this doesn’t apply as you stated at the end of your post.
I appreciate all input opinions and help with this project and forgive me if I ask questions bc it’s how I learn
