164 24 valve engine.

Ask a silly question, but what is the difference between a 12v and 24v.
Would it be a straightforward swap for my Corse I apart from top end differences.

I suspect it's not worth the effort for the minimal gain that would be achieved.
Run the car as it is until you get it shaken down & set up as you like. There are more gains to be had from a well set up car than there are from an extra 20hp. Once you've proven the car and if you still feel you need more power then look to a phase 2 or phase 3 engine rather than a 164 lump.
