200 4R question

[Cornwallrc]

Hey guys, Just looking for some quick help, I'm swapping out the tired TH350 from the 72 and replacing it with a 200 4R so we can enjoy the OD and lock up converter for road trips.. My question is, the ID Tag on the 200 4R is CZF From an 87 Monte Carlo SS. I've read that they have a special (better for performance) valve body, plate, 1-2 servo, 3-4 servo, 2-3 intermediate servo, and governor. That being said, Should I still purchase and install a Shift kit for it prior to installing the tranny.?? Is it needed?? I was thinking of purchasing the TransGo performance shift kit from Summit.. Suggestions? Reviews??
