briggs 33 vertical valve clearance

[38racing]

valve clearance seems to always show as 3-5 In 5-7 ex for briggs ohv 28 and 31 series but in the briggs manual it shows 3-5 for both in and ex. Does that make sense or maybe a typo?

update: just found at manualsonline what looks like an official manual for 33R877 which is exact model I'm working on and it has the 5-7 for the exhaust.
