V8s headgasket and cam options

[V8sweep]

Hi everyone

I'm looking at replacing the headgaskets and our V8 , can anyone tell me the correct gaskets , I had bought a set (composite type) but the more I read the more I get confused with all the RV8 options!

Also I'm planning on changing the cam and lifters etc to freshen it up . I was looking at Real steel viper I think but does anyone have any other better options I don't really want to change double valve springs or pocketed Pistons .
And another quick one , are the RV8 headbolts reusable ??

Thanks
Kate
