Sean is correct, if you're going to run oversized valves, go with larger exhaust valves. There's math involved but it boils down to valve/bore ratios and your intake/exhaust ratio. If you run a massive valve on a small bore you're going to shoot yourself in the foot because the valves get so large that the air has a tough time getting around them to get into the cylinder.
Last year I ran through all the calcs for where the best improvements could be made and the stock intake size is fine for any engine using a bore smaller than 87mm. The exhaust would benefit slightly from a +1mm valve but it's not necessary. You'll gain WAAAY more with a good port job vs larger valves.

Unfortunately I've been out for weeks and had no news from the mechanic.
I never put in doubt these choice, because he is 4G63 expert with tens of builds behind.
But I try to meet him tomorrow just to fix this point, because if this is proven I would follow it.
Let u know soon

It's not the end of the world if he already did both. More just extra money that didn't need spent.
