2.02 or 2.055 valve?

first go with the larger valve it help you out on the high end

second the cam you are gonna use will need more stall
than 3500 at least 42 to 4500

I usaed that cam and it didnt have any bottom end
centered in any way to much duration

and if you get more cr. will say 11.5 to 12.0
it will get more hp and torque

my 2 cents
