I would go with ferrea. Im in the process of doing a lot of research in purchasing valves for my supra. I dont have the time to get into detail as im walking out of the door but the ferrea lineup looks to be leaps better than supertech.

I wasnt sure if you were just paying for the name with ferrea but that is def. not the case. Their stuff is sick.

 

Thank you all for your input I've decided to go with SuperTech inconel exhaust valves, bronze guides, AP2 retainers and keepers.

With those new valves, will a valve job be necessary? Or would lapping them in be sufficient?
