The head is for an Oldsmobile with a stock 6* valve angle. On the left you can see an inside and outside port with the stock floor location, on the right I've welded them up to about even with the start of the SSR.
I'm going to defer to the porter's decision on if this is beneficial or not, but I can't quite get my head around whether or not this helps shape the SSR to avoid stall. I know stock Olds ports generally stall around 0.550-0.575" lift, but the Edelbrock port is a better design, especially in the bowl and SSR.
I am a complete novice, but I haven't found an in-depth discussion on this and I'm not sure if "raised runner" heads generally have a higher drop from the top of the short turn to the throat? I can weld up the short turn if necessary but if I don't have to touch this critical area I'd feel better!
