What are some signs to look for in a defective head? I bought a b16 head from a ht member (jdmtuner4life) And i wasnt impressed with all in the quality. Head was pretty much bare. I paid for complete head,got head,cams, valves,springs and retainers and a few plates to seal the cams down. Alot is missing,but im probably just going to roll with it since there is nothing i can do now. But im going to be using this head on a crvtec plus turbo,and i dont want to use something thats all fucked up, what can i check to see if its defective.

 

Maybe its just me, but if I were building a setup (and i did) I would replace everything I could.
Have the decking checked by a machine shop.
Replace the valve seals and even the valves themselves if youre suspect.
Valves are easily checked for their straightness when you pull them to do the seals

 

Checked them all,seemed to be good. I dont want to use the cams though..seem to be rusty?
