150 is attainable with some cams, smallport don't make huge gains over bigport.

ITB's are a no go on standard ECU without extensive modification, only ever met 1 guy who knew how to do that.

There are no different versions of the bigport head, they are all the same where it counts. It's just appearance and mounting points where there are differences.

Thx for the website they still have a few interesting parts, sadly the pistons are not available anymore on amayama.

And it's good to hear that 150hp are quite easy to obtain.

I read from this 1 guy.^^ He was really skilled but at this point it's easier to change the ECU which also has more advantages.

In regards to the bigport. Ok so there are different versions but no major differences.
