Need recommendations for 71 C10

[Woodinc]

I just purchased a 71 C10 350/350. I need to replace the water pump and starter and have already replaced the battery. I'm going to change the thermostat and oil at the same time. The air filter looks new but I think I will replace it also. While doing the water pump I'm going to look at the timing cover to see if it is leaking and repair if necessary. Do you guys have any suggestions as to anything else I should look at while I have the front of the motor off?

Thanks,

Todd
