Couple Rebuild Questions

[skokz]

I plan on rebuilding one of my 318 in next few weeks. Its going to be stock budget rebuild.
This website list a rebuild kit for 67-73 and 74-89 318s. Both kits are same price but they are different part numbers.
I have a 72 and 74 318 both need rebuilding. Whats the difference between kits?

Also when I had everything apart I was gonna get a cam. These are the two I was considering.

SUM-K6901
Cam and Lifters, Hydraulic Flat Tappet, Advertised Duration 276/286, Lift .441/.441, Chrysler, Small Block
SUM-K6900
Cam and Lifters, Hydraulic Flat Tappet, Advertised Duration 262/272, Lift .420/.442, Chrysler, Small Block

Im not putting a 4 barrell carb or intake on it. Everything is going back stock. Only thing that will get changed out would be the stock manifolds for dakota manifolds since I have a pair already.

So will either one of those cams work with the stock heads and 2 barrel intake?
Which rebuild kit should I order or is there even a difference?

I would use the smaller cam in a 318...especailly with a 2 barrel
