Ferrea Stainless Steel Valves for 1uzfe heads

[Lextreme II]

I just ordered a set of Ferrea for 2JZGTE for my SC470TT 1UZFE heads. I got 16 stainless steel stock size exhaust valves and 16 1 mm over size intake valves.

The stock 2jz is 1 mm over larger then the 1uzfe exhaust valves. However, the intake is about the same for both engines. Therefore, 1 mm over size will work on the 1uzfe. I will have some pictures when I get them. Please read more in this page

But the valves are still too long?

We will modify the cams to compensate the length.

Indeed they are too long. In fact way too long to be able to compensate with any cam modification. I had a chance to compare ferrea 1mm over intake valve next to a stock 1uz intake valve. And well.... I'll post a picture so you can see for yourself.

Alright good to hear of some possibilities being worked with here. Maybe we can get a few of us to go in on a few sets of oversize valves made for our purpose. 1mm over is what I've had in mind.

I'd bent one valve in my BMW R100RS road-racer,
called in - drove there - installed a new valve that
same day - 'Custom Cut' - :yeah:

Got my Supra SS valves few days ago. They are officially 1mm over size for the 1uzfe heads. However, they are slightly longer but we will make it work.
