If the previous pads left black rubber burnished on the rim sidewalls, that could causes squeeling. Scrape or sand it off.
Any anodizing on the rim sidewall can also make for more tendency to squeek.
If the rims are chromed, the salmon pads will always squeek.
Observe the alignment geometry of the pads withe the brake applied lightly and with the bike being forced foreward.
This is the condition where the pad alignment counts.
You will need more toe-in with stickier pads in most cases, since sticky pads tend to be more squeeky.
