Aod To Fmx Swap?

I have 3.73s in it now, I'm gonna be going through the entire car though eventually so I may end up going with 4.10s. I need to get the damn car running right first to tell you the truth...I had to completely re-wire the EFI harness, then put in 30lb injectors without an upgraded MAF like an idiot. I still have to put the stock injectors back in...plus I got an 80mm Lincoln MAF, adapter and cone filter to put on. I'm not quite sure if the transmission is shot or not...it has an aftermarket TV cable and I haven't been able to adjust it properly yet. It shifts way too soon, most of the time I have to shift manually, and when I shift from 1st to 2nd the transmission goes straight to 3rd. If I can get everything adjusted right my tranny may be fine for now as long as I don't track the car. Any suggestions on adjusting the TV cable?
 
I really need to upgrade the valve train as well, as I'm running an aftermarket cam with stock E7 heads. I thought about getting the TFS valve spring kit and some rockers...the guy I bought the car off of didn't remember what cam he put in the car and lost the receipt (lol) but he said he did a cam and lifter package...I'm guessing it's around .500 lift or so, nothing serious obviously. I've heard mixed reviews about the retainers on the TFS kit, does anyone have experience with them? Also, should I go with stud mounted rockers and get the stud mount kit or stick with pedestal mount? It seems that there are a lot more options at a better price for stud mounted rockers, I would probably spend the same amount of money going either route.

I've got stud mounted rockers because my Eddy heads came with studs. I see no advantage or disadvantage of running either vs the other. But I'm no engine expert so maybe someone will come in with some good info lol
