360 J head 2.02

I have a set of 360 j heads with the 1.88 intake valve. I recently came accross a set of 2.02 intake and 1.60 exhaust valves a a good price, which i purchased. I was wondering what are the advantages or disadvantages of cuttin these head out for the bigger valve. Keep in mind I am building a 360 for mostly street use and little track time.
