I just installed my intake and relized after doing more reading that I should have put Sealant around intake ports. Will I be able to unbolt and clean the china wall sections put more rtv around the intake ports and again on the china wall reusing the old gaskets?

 

Maybe. If they rip while removing.....no.
I'd just get a new set. No sense in thinking they're fine only to find out that it's leaking after you have everything back together.
