Can you get them new from Toyota? Whould anyone take on this kind of work?

Take into account that brand new Toyota valves are quite expensive new and there are 16 of them.

If it is beneficial going with larger valves on the FTE that has to be seen but I can't see why an experienced performance engine builder wouldn't take it on if you really wanted to have it done.

I'd have a consultation first to find out more. Good/helpful places do exist.

Ginchey I currently researching the same thing...only help I came across so far was something like using the 4age valves...but you have to cut the length..I'm not sure...I'm presently trying to get my hands on one to measure and experiment. will let you know of the outcome...

by the way I'm new here.. I've only registered a few minutes ago.. so plz excuse me if I'm not on par with you guys on all the technical info.. I'll share what I do know ...

There are many things to consider to make this work.

Unless you really need them i'd say stay with stock. Which are good for over 400hp, with the correct head work and cam's.

Let me know if you need some more 4AGE valve info/dimensions, I've got them to hand and can measure them up for you.

I've also got the oversize ("formula Atlantic" ish) valves, where I've been building a big-valve 7AGE!
