Well if you have located them just change eip to pushad/push eax... decrypt code and dump it =)
I've used hiew to scan for pattern in optimik and just redirected eip to those addreses, dumped them with ice-ext and fixed dump
or event better would be to code debug loader if there is more then 20 crypted code places and automate process of eip redirection/code dumping.
cheers
