Your steps sound good. Problem is that the CIS pistons are going to get in your way. Those are going to have to go and probably when you do the EFI. Though I guess you could EFI and stick with the CIS parts... need to get an answer on that question. But, if you are changing pistons you might as well get bigger stuff. Also, if you are twin plugging the heads you might as well take the whole engine apart. In my limited experience, the top end is the hard expensive part. Bottom end and case is easy.
The really nice thing about ITBs is they look and sound REALLY cool and the install is a lot cleaner. A hacked up 3.2/3.0 intake looks exactly like that... a hack job. Don't get me wrong here... they work great! and are a cost conscience solution that you should consider.
I'm not sure, but you may want to combine steps 2 & 3. Cost may prevent it, but you may save inthe long run.
Best reagrds,
