Default Gt 05 heads on 5.4 modular block?

Hi all, newbee here been asking everywhere but not getting good advice, found a great write up linked to this group forum on 4v heads for the modular engine, so here goes again 😃

I have the Australian 260 boss engine I want to supercharge, my initial thought was to remove boss intake x re, position alternator and buy gt500 intake with intercooler and fit eaton blower etc, I've got the c type heads, 04 engine, blue tick on heads

However I've just been offered a deal, gt heads 05 apparently with a intake with 16 injectors? Heads look to have had lots of work done to them also, will try to to upload pics,.

Am I going to have any gain from not fitting gt500 intake onto my stock c heads? Or would i be better in buying gt heads and intake and fitting 2.3 Keane Bell blower?

Will 260 boss stock internals take this power ?

What are these fr500 heads people talk about ?

Any help would be appreciated
