The ports could be built up with epoxy putty. I've seen that done on race heads. Flow on exhaust ports doesn't matter as much as intake, so should be no problems there. Port matching the exahust manifold could be critical if the manifold opening are a bit smaller that the ports, but if the manifold has larger ports it could actually help. 

Thanks the chamber volumes Andrew! I forgot to look those up last night. 10cc won't give much of a gain though, not enough to really notice.
