Depending upon exactly what type you're talking about, they'll probably fit.
Going to 1.6:1 will likely not result in a quantifiable improvement in power, and will likely overwhelm the stock valve springs.

Re: roller tip rocker fitment
I suggest going full roller 1.5 rockers. Stay clear of those 'roller tipped' rockers. The full rollers have much less resistance where it really counts. Wait to get 1.6 rockers until the heads are replaced with valvetrain that can safely handle it.
