I got a used 1g head off a blown motor 1g. I don't remeber the exact cause of death of the 1g car, but I do know he ran 18 psi of boost on a stock ecu, stock fuel injectors, with no tuning software. I guess we can safely assume he ran really lean alot of the time. With that said, how do I know the head is any good? is it something I can visual check and if I don't see any bend valves, I am good to drop it on my new engine? I rather not spend money on new valves, valve stems, ect because I want to use stock bore size on the head (im building for low end torque) anyways. I plan on running evo springs and retainers since that is just an easy swap while the head is off, and 3g lifters. Is there any other things I should look for or buy to have this head read for my car? and can anyone tell me the benefits of lighter evo springs, and 3g lifters. As far as I know, 3g lifters don't "tick"; any other benefits? thanks, and here is my build thread for any of you who wish to give my guidance with reference to my road racing goals. http://www.dsmtuners.com/forums/hangout/332712-2-4-liter-g4cs-build-thread.html page 1 twards the bottom is the only good pictures I have it atm. and that doesn't even show you the bottom and valves.. I just see golden dirty and want to clean it.
