What cam would you run?

The RPMs are good the way they are for a lot more cam than you have - but there's no point in going any bigger unless and until they get ported. I would suggest that an 8" convertor would be a much better choice given the weight and gearing, and will hit harder and be more efficient (slip less) in high gear than the 9.5. You might ask PTC about trading that one in.
As far as the rockers go - I like using 1.5 rockers. Some disagree but I'd rather get the cam I want rather than worry about the issues with more ratio. The cams I would like for this are larger and the 1.6 starts to really push the lift beyond where it helps any and it's harder to find a duration in a cheaper non-custom grind to get the .540ish lift at the valve and still have decent duration. Ratio does not do much in terms of changing duration figures.
