I would agree with you. I don't see the 60mm raised cam as being a big benefit to you. Yes, some guys think they are sexy, and I guess so do I, but it all has a cost. And it adds complexity to the build. Complexity adds time and alters the fit of other parts. Sometimes guys just like throwing money at something for fun. I use titanium studs and nuts to hold my carb on. Does that make sense? No. I just like to waste money on sexy stuff. I believe you are overthinking this. An engine like you are describing is something that Ray Barton has built hundreds of times. Hundreds of them on the dyno. He knows how to get where you are going. He makes it too easy. I bought a Neon with a Ray Barton 572 in it. 975HP (more cam than you want for your application). It was nice.
