Pretty sure the original production HO intakes were the same castings as the iron and when either is ported by SD they are great intakes that can support up to 600hp according to SD.

Both '72 HO intakes (485640 & 488945) have the higher port floor like the later SR al intakes. You can see the indentations if you flip it over. The indentations don't exist on the 69-71 oem al intakes. but the 69-71 al casting required a bit shallower floor over the iron intake for the crossover packaging....that height is probably what Cliff measured....
