Just buy a pair of 2nd hand CT12As and put them in.
Cheaper and less hassle.

are you sure?
the dump pipe flange and possibly the exhaust manifold flange appear to be different:

before buying two used CT20's -i'd check that they'll actually bolt up (e.g. right flanges) and that your budget also allows for new/other dump pipes and possibly manifold as well.
... i dunno about HG - but my limited experience with alloy-head motors is that you may have to have repair (welding) work done on the head if there is corrosion between water jacket and elsewhere. But if it;'s just the gasket, then probably doing nothing apart form cleaning valve-faces up would probably suffice.
As per recent threads about 1G performance upgrades, there's a lot more to be gained from upgrades outside the engine (turbo, exhaut, computer, injectors, etc)
