Ideally if port design allows it, isn't valve/throat should be mcsa ?
Yes and that port would not have a push rod pinch but as mentioned we have to work with in our constraints

I appreciate the post and the interest. I’m learning as well.Absolutely! Understand my intention was not trying to upstage anything, I really thought it was useful and this was the best place to put it seeing how much work and analysis you've been putting into this topic. Always trying to learn. Someday i want a bench but until then the only bench have is the one I sit on.
I would have to go back and check, but I believe the pushrod pinch in the smallest in most small block mopars. The apex area at the top of the short turn is the biggest problem however. There is a little bit of time for the air to expand and slow down after the pushrod pinch. Not so after the apex. Ideally, the area at the apex should be larger than the throat area. If it’s the other way around, the air is expanding as it goes over the short turn. That is a recipe for disaster - separation. After the apex the port needs to converge. This controls separation to some extent.Well, the perfect port would also be a straight run cone, no? We have to play the cards we're dealt with kut engines. If you look at just about any of these ports, the smallest area is between the spots right before and after the SSR.
