You should be fine running that comp on 98 provided the tune is good. I used to run a Pug 205GTi on 98 which had 12:1 comp and it was an old 8v SOHC engine with a poor chamber design. Admittedly I had a big cam (296deg duration) and quad throttles.

On a far superior engine running the same comp or more shouldn't be a worry if the tune is right. Not so sure about doing it with standards cams though. That may push the boundaries a little. You may need some cam to reduce the dynamic compression as was mentioned in a previous post.
