I had some leaky seal issue on my '03 450 EXC. It was not literally right
after they were changed (not when right after picking them up from the shop at least).
I tried Moose seals, bikemaster seals, but then a guy out here in California that
builds suspensions (Precision concepts, met him on KTMtalk), suggested Synergy seals. He installed them, and change the oil. I never had leaks
afterwords. I can't say if that would help your issue, but...

You do bleed the air out of the forks after long rides?
