i swapped out my z6 head with another z6 head and now its smoking white like crazy and sounds like a tractor and 4 valves are locked up what do yall think it is? i heard head gasket and bent valves or head bolts not being torqued right let me know.

 

Sounds like you did something wrong when replacing the head and the head gasket Isnt properly sealing. Your replacement head may have been overheated and warped.

 

how could it be overheated and warped if it was checked for that and resurfaced?

 

If it was checked and resurfaced than you shouldnt have that problem. I think your headgasket isnt sealing properly did you use the right torque sequence and torque the head bolts to spec?

 

Does it smoke all the time or is it just when v tec hits?
If all the time head gasket if v tec then welcome to the world of v tec!!!
