Technically you don't HAVE to do anything other than the gaskets, rockers (different type), pushrods likely, and measure for PTV clearance. That said, you haven't stated your goals or problem statement, just a generic post asking for someone to give you all the answers... more info would be helpful to guide you.I got a stock 90 Mustang LX 5.0 (except cam), So what is all the supporting part that I will need to upgrade?
Thanks for the reply. My goal is to make a little over 300 ish. I know I’ll need to upgrade my fuel pump, injectors, Throttle Body, MAF Sensor. I want to know what parts will be the bottleneck. What pushrods, roller rockers I’ll need.Technically you don't HAVE to do anything other than the gaskets, rockers (different type), pushrods likely, and measure for PTV clearance.

I thought I will need a 70mm MAF and Throttle Body.You will need a better fuel pump sooner rather than later.
Pushrod length will need to be measured when you install the heads, as will piston to valve clearance.
Stock rockers, injectors, throttle body, & MAF will work for 300 hp.
ThanksYou mention the cam you have isn't stock... what is it? That is one of if not THE most important part of how the car will drive on the street and how easy it will be to tune it, not to mention where and how it will make power. You didn't mention how you'd like to use the car either, street/strip/auto-x/road course/other?
I'd recommend talking to Ed Curtis at Flowtech Induction as he can put together the entire package for you designed to meet your goals. Or go with something like the off the shelf Trick Flow Top End kit which will give you about 300 RWHP and then you just need a new fuel pump, injectors, and tune.

Oh, I do have a T5 transmission on crack.There is a bunch of info here: https://stangnet.com/mustang-forums/threads/technical-thread-how-to-index.808661/
There is more to it than just having a HP goal like where your HP and torque come in at what RPM range, also factor in trans type, rear gear, ignore these things and you'll likely end up with a pooch that will not pass a golf cart.
They will help, not a requirement for 300 hp. Removing each bottleneck gets you a little bit closer.I thought I will need a 70mm MAF and Throttle Body.
If you want to get the most out of the combo I would recommend:I got a stock 90 Mustang LX 5.0 (except cam), So what is all the supporting part that I will need to upgrade?
If I were have to guess what cam I have, it's probably a E303 with an addition of an op transmission.If you want to get the most out of the combo I would recommend:
Headers and mid-pipe (shorties are easier and cheaper but long tubes will make more power)
Upgraded fuel pump ( a 155 will be plenty)
ARP head bolts or studs
stud mount roller rockers, ratio depending on what aftermarket cam you currently have
new push rods and lifters (I have AFR 165s and used stock length Comp push rods and Ford racing lifters on mine)
New gaskets of course. AFR lists their recommendations for gaskets here:
AFR 165 head recommendations
Send that Explorer lower to Tmoss for porting or follow his guide and port it yourself
30lb injectors
75mm MAF calibrated for the injectors
65 or 70mm throttle body
What cam do you currently have?
You COULD make the stock injectors, MAF, fuel pump, and throttle body work but it's going to really restrict the potential of the combo. There's a reason the engineers at Ford used a larger MAF, throttle body, and injectors on the '93 Cobras.
Basically a T5 Transmisison on crack.“op transmission”?
'On crack' is a nutshell on how I explain it. Basically, the transmission is so strong that I don't rev match it, instead I mph match it.Basically a T5 Transmisison on crack.
