I'm replacing a carbureted EA82's long block with a long block from an EA82 SPFI. Will the carb intake match the SPFI heads where they bolt together?

The intake will bolt on fine and they use the same castings. However, the SPFI heads DO NOT have the bosses drilled for the emissions stuff that's on the carby model, the two pipes that go down the side of the engine. The hole where the pipe bolt on is not machined through and the bolt holes are not drilled or tapped. I ran into this first hand, I just went and got a carb engine. I didn't try to drill the holes (probably would require removing the heads at the very least) out or bypass the emissions, both are probably possible but I didn't want to mess with it.

I don't mind doing a little tapping but are you saying that i'd be tapping into the guts of the head? i was under the impression that all i had to do was thread a few bolt holes that weren't actually drilled into the head, just into the surface of the head.. ??
