M103 refresh tips

I'm doing a head gasket and rings w/ bearings if it looks like the bottom end needs it on a 3.0 M103. While its out are there any tips/tricks I can do to pick up a little power? We're restricted to running a M103 with the "stock head" in this case but I can mill it and I was thinking about looking into the ports to see if I can clean them up any. I've never been a big believer in expensive multi angle valve jobs but I could be convinced otherwise.
