Bunk,
Your welcome!

But please keep in mind that you may need to raise the seat/open pressures of what ever spring you end up using to keep up with the new 1.6 rocker arms and 6000rpms.

Did you receive an answer to how much spring pressure to use with the 1.6 rocker arm swap?
If not, here are a few contacts that you can use to confirm that you are using enough spring pressure for your new 1.6/6000rpm swap. Just get them the details of what you are doing and ask for their spring pressure recommendations.
