But let's say I did buy a 52mm throttle body , would I have to alter the intake or heads? Because I don't want to just yet

If you do a larger throttle body on a stock engine, you'll see zero benefit other than your wallet will be lighter by the price of a useless (to you) piece. Stock is good for a bunch of horsepower.

Or are you going to be one of those news who thinks he has it all figured out and just wants us to tell you how to do what you have decided is best, rather than have us help you make choices more efficiently than we did.
Far as the actual question 52mm is the biggest fit without any mods, 54 or 58mm are easily accommodated with minor inlet porting that some have even done on the engine but the waterless intake is easily pulled for cleaner porting.
Then there is the question of which TB, for 52 or 54mm the ONLY choice I would make is rebored stocker as they work better than almost all the aftermarket ones, but gthere is still the argument of since 58mm is easily accommodated why not go all the way to that. Or a stock intake can be opened up more to accommodate a 1300cfm monoblade, but that screws up the idle air distribution which is a hassle to resolve for a street car.
The best advise anyone can give you is to ask meaningful questions and LISTEN to thoughtful answers.
Just telling you a 52mm fits without modding the stock intake or that the stock casting can be slightly modified to accommodate a monoblade doesn't address that most of the aftermarket TBs need mods to work right, or that without adding 150hp+ a larger TB is of questionable benefit.

Why not wait and do the TB later when you can do it more completely?

I'm pushing 414rwhp through an untouched stock throttle body and intake. Focus on other parts first.

That's why I asked, I thought you were talking about the entire radiator support, not the cover.
Here's one.

OP
your title ? was
" what's the biggest mm throttle body i can put on a stock LT1 intake ", which I answered.
You got further comments including from 96caprice. His points are true regarding the benefit of a larger TB on a basically stock car (your CIA and exhaust don't warrant a larger TB). Albeit some comments may sound harsh just understand if you do decide to go larger TB you will need to have the PCM re-programed regarding transmission line pressure or tranny failure will follow.
My $02, beyond just your initial ? is you will see no "performance" benefit with a stock motor. heads/cam, more CI, headers than they start to become of "performance" value. I would wait until performance mods are done before just putting one on. My $02
