how much different are the heads of a vq30de and vg30de? i want to get some springs, retainers and valves but jun on has them listed. would go with jwt but juns seem to be cheaper and i have heard more about jun heads than jwt. and would any sr20de parts be applicable to our motors since some of the drivetrain parts are the same?

 

Parts from a VG motor won't work in the VQ, same goes for the SR. Some injectors might work but NO. If they were compatible don't you think tons of people would have already bought them.
