Intakes are mostly the same, no issue there.

Take a caliper, set the piston to half height (when removed the head and buttonhead. Set the back end of the caliper on the edge of the sleeve and push down the pin and push the piston to the point you see a glitch of the upper edge of the exhaust port.
Keep the distance in mind or with a digital calper set it to zerro. Then push it way down to BDC en read the caliper, that is the height of the port. With your R03 it will be 7~7.2mm.

Do the same with the new set, I am almost sure it will not differ much, with a higher port you will get a tiny bit more RPM but also loose a tiny bit bottom power and with a lower port otherwise.
