1976 3.0 Si emissions control devices

I recently acquired a 1976 3.0 Si that remains equipped with all its original emissions control devices: air pump/thermal reactor, EGR system, etc. Has anyone here gone through the removal of all these devices on a M30 engine? Any words of wisdom?

Thanks for your replies. I don't yet have the car so I've not inspected the head up close but it doesn't appear to be cracked as none of the familiar symptoms are there but I would be very surprised if it is the original head for the reasons you mention.

I'm planning on removing the air pump and reactors and perhaps the EGR devices. I imagine E3 exhaust manifolds can't be that hard to come by although I prefer not to have to buy a whole parts car to get them...
