k guys Im doing a mini me swap on my sohc zc block. I got the head yesterday but just need some info on stuff I will need

-What are the bolts called that hold the vtec solenoid cause I didnt get those with the head
-Would u guys recomend getting a cam (stage 2) with a valvetrain kit or should I just leave it. And what kind of extra performance would I be achieving by getting cams and valvetrain
-what is the best way to clean the head (myself) and do I leave the valvetrain in the head when I do clean it or do I need to take some or all valvetrain off

Thanks
