Oversize valves and oversize port ?

Hi all,

I need little help
I make SuperTech oversize intake and exhaust valves of my S50B32.

I need enlarge the port from intake and exhaust or is ok whit original size?

Of the RB26 (Nissan engine) if the port is enlarged that the same size that oversize valves that give not great results but of VW engine is better that all have the same size.

HELP 😭

If you want to have it ported and done, let me know- but it won't be cheap from France.
