Go out the box, run the CTR with the 404's and e85...
Edit:
What made you think GSR piston? So many better choices...
Just running on a really tight budget and the 81.25 block and 81.25 GSR's are what I already have.
I don't really want a crazy compression ratio, any way.
This set up should put me at about 10.6 : 1.
That's plenty for me, for right now.
