1.6 should work as long as you have enough spring clearance between the coils. Be sure to check before you fire the engine up.

Re: 1:6 rockers?
1.6's will be fine on a stock setup. No clearance issues. All that factory equipment was way to small. Handful of HP gain.
Cam swaps aren't a walk in the park, depending on what tools you have available. Depending on what cam would go in, it's the tuning that's more or less the 'fun' part. Also, with stock heads, you're stuck at .480"ish, sometimes less, of lift that you can safely run before retainer-to-guide boss interference. So this kind of limits cam selection to begin with.
