Is there any flow or noticeable power benefit to completely removing the pushrod pinch in an Edelbrock small block head, like the way this one has been hogged out?

It looks cool, but I don't know how much material there is left behind the cut...it's probably getting pretty thin there? Maybe they're welded...don't know yet.
I have not seen these heads first hand yet, only in pictures so info is pretty limited.

I'd think it would be a good mod to do, but sometimes what looks right doesn't really work right....

I looked at the pics on Ryan's page and this one looks more agressively opened up though not as pretty as his, so I don't know what to think.

Thoughts?

Thx
