Jetting on 440

[schuie]

I have just bored my 400 to a 440 with a Hotcam Stage 2. I have a WB R4 slip on, and a K&N with a close air box. I was wondering what jetting to use.

My altitude is about 1000-1200 feet.

I was also wondering what jetting to use with an open air box. I am thinking of opening it up.

Please Help
