Basically wondering what compression figures I should be wanting with a ported engine, I've currently just got to 1000miles so I'm run in and about to do a complete service, with all oils, filters, plugs and washers.

Will be doing my first compression test @ 5000miles for my baseline!

Just want to know what is best as I know ported engine run lower conpression!

I suspect that depends on how aggressive the porting is?

It shouldnt change at all unless you got really aggressive.
