The aftermarket EFI tanks may be slightly deeper than factory in some cases, but it would take a really trained eye to notice that it's not a factory tank. If you're worried about concourse judging with something like that, the simple addition of the efi throttle body itself is going to knock you as well, so there's no real reason not to go with the efi ready aftermarket tank.

I've had two tanks inc tanks myself. The one in my firebird is 10 years old and is still in outstanding condition. I also had a tanks inc tank for my wife's 70 Chevelle. Although we no longer own that car, it also held up really well. In the case of both tanks they were both very close in size, shape and design to the original tanks they replaced. I can't comment on if that's the case with their offering for a 67 A-body.
