Orange-ish coolant, remove head to inspect? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Situation: s14 SR motor on a stand. Removed radiator, coolant came out pretty rusty. Then, removed turbo lines, concentrated orange liquid came out (really heavy orange). And lastly, removed water neck, a lot of rusty build up inside but easily washed off.

Suggestions: what would cause such rust build up in side the engine, headgasket? or the previous owner never change coolant?
Should I remove the head and take out the front chain/oil-pump cover and inspect?

Currently went of cash for this swap. Should I just fire it up and change coolant and frequently until I fix it when I save enough for a engine build?
