"...I might install a 1969 intake on it this weekend..."
A '69 intake will not work on '72-up heads, without mods.
The late heads have a blind hole, above the exhaust heat riser holes. The '71 & older intakes have a large rectangular exhaust crossover hole, on the passenger side, which will cause a leak.
There are fixes. The blind hole can be filled with furnace cement or equivalent. Some say you can cut a thin stainless plate, to cover & seal off the pass side holes. I've even read that some have used the Fel-Pro 1233 intake gaskets. I haven't used any of these methods. So, I can't say what will work best, or even that all 3 methods will work.
