How healthy is YOUR engine? If you are still driving a stock head setup, especially if you did a 2JZ swap in your project car, it's certainly seen some mileage. As bulletproof as these engines are, they do still get tired out over time, especially with abuse, lots of boost, and poor maintenance. Here's a great chance to start FRESH with a refurbished head.
This head comes complete with a great usable core (if you're looking to build it), intake and exhaust valves, stock cams, valve springs, guides, cam caps, etc. as pictured. Or if you're doing a relatively stock build, it's basically just a bolt on!
