Timing belt/water pump job time

[Cascadia]

So I’m having a shop change the timing belt and water pump on my LJ78 (2LTE). They’re working with my parts and just charging labor. I’m wondering if anyone knows what I should expect, what’s unreasonable etc.

Plan minimum 5 hours labor. Should be right

Sweet, thanks.
