I'm looking to rebuild the top end on my 08 and could use some help. Should I be buying a rebuild kit or aquire parts separately? I hear that oem gaskets is the only way to go. I can only access 91 octane fuel not sure if I could bump it up a few points with some additive. Would a 12.8:1 piston do the trick or should I remain stock? I plan on cleaning the oil screens and possibly be replacing the cam chain. Any other suggestions would be greatly appreciated.
