I agree with you about the "vintage" emissions control devices. They seem to be more vacuum drainers and power loss devices than anything else. The only catch (Catch-22?) is, do you need them to pass inspection in Callie-Fornie? I'm never sure how all that works, no matter the state, and especially CA. Save the pieces!!!

JD is right, save the pieces. The California DMV process seems complex at the start, but after you go through it a time or two with the info available online, it becomes clear.
Your MGB looks like a '71 or '72 to me, Nick. I had a '72 and the SMOG stuff is minimal in those years. What you need to have on board at the time your Locost goes in for it's SMOG check (and you can't avoid having one) depends on whether you register it by the year of the engine (donor) or the year of the car (your chassis model year). Which of those you use depends on what SPCNS sequence number you have. If you are one of the first 500 SPCNS registrants for any particular year, you get to choose: engine or car.
So, if you have SPCNS sequence number = 500 or less and register it by the car model year, and the car is a replica of a 1963 Lotus 7 (hint, hint), then the required engine SMOG gear is zero because SMOG controls were not required in 1963. Obviously, in the case of a 1963 everything is free and you can put a Roots supercharger with a fuel injection throttle body on top if you want to (not recommended).
You will have to have it SMOG checked by a California BAR approved site where they will note the emissions for state files, but never check your vehicle again. That is, you will essentially be exempt from there on out. Should you end up with sequence number 501 or better, you'll need the SMOG gear from your donor (MGB) to be in place and working at the time it is checked. You will be checked every two years thereafter just like any other car of that engine vintage. It is no longer the case that pre-1976 cars are exempt. You will be required to pass SMOG every two years.
Confused? We all are at the start, but it becomes clear when you read it a couple of times and read about the experiences of others.
Here is the over-all SPCNS process ==>
