Hey guys, i blew a plug on my 01 bullitt and am going to order tomorrow new patriot stage 2 heads. I just nee to know everything I should order.

my first question is that my block is a Romeo block correct?
I am ordering Patriot stage 2 heads the assembled one's and it says *(Sold less rockers and lifters). I am not sure what the rockers and lifters are. do I need these? what do they do?
I am also going to get their Patriot Performance Modular Ford Billet 233/237 .545"/.550" 113 lsa Cams. Do I need the Patriot Performance Modular Ford Adjustable Cam Gears or Ford OEM Bolt-On Cam Gear Kit that they also sell? and do I need anything else or should do nething else while im into the engine? thanks alot for replys.
