I need help identifying what intake valves I have. I bought this head a while back and we were under the impression it was a B16 head. I think it's an ITR head b/c I have found the vavles springs to be ITR and also the cams are ITR. I started taking out the intake valves last night and saw that they look like ITR valves as well. They are deshrouded by the head of the valve. They also seem to look similar to supertech though. The tip of the valve looks different but is def. coated on the and the back of the valve head. I didn't see any markings on it so I assumed it was ITR which would mean that my cast is most likely ITR as well. The intake ports look pretty smooth. Not too smooth but smoother than the other heads I have.

 

They look to be....can always weigh them. They are almost 2 grams lighter than b16 valves. I think aftermarket ones like ferrea or supertech are even another 2 grams lighter than itr's. Dont know 100% if thats the case but pretty sure.

 

I didn't even think to weigh them out lol. I'll see if I can find some info on how much they do weigh and give it a go.

Thanks

 

supertech valve will have a logo on the top of the valve
