depends what you want to do.Originally Posted by sum1udontknow84
Usually, i reccomend valves, valve job, springs an retainers (I only use Skunk2 PRO or Rocket Motorsports) cam seals, valve stem seals.
depends on how many miles is on the head as well. If its got more than 100k on it i would def get new guides installed as they tend to wear out pretty fast.
