Piston to valve clearance may become an issue if you run the 1.7 rockers with a high lift cam. I wouldn't worry about it though...unless you plan on sticking a huge cam in there. If you are leaving the stock cam in place than by all means jump up to the 1.7 rockers. But if you are swapping out the cam for a more radical profile...you might want to stick with the 1.6 rockers.
