5SFE Vavles swapped for 2JZ will it work?

[MyFreeCamry]

I have heard in a couple of conversations that 2jz valves will work in a 5sfe head with head work (of course). Here I have listed the specs of each valve and need help from someone to determine with springs, retainers, guides, and locks to use. Also what will need to be done to the head to make them fit. I am trying to compute the numbers myself and am only making myself confused right now.

5SFE HEAD
INTAKE VALVE- 33mm head diameter x 97.5mm stem length x 6mm stem diam
EXHAUST VALVE- 28mm head diam x 98.5mm stem length x 6mm stem diam

2JZ HEAD
INTAKE VALVE- 34.6mm head diam x 98.55 overall lgth x 5.98mm stem diam
EXHAUST VALVE- 30mm head diam x 99.1 overall length x 5.98mm stem diam

What do you guys think? If I can figure out what to use, I will make this happen.

Why don't you just have Ferrea make them? I wouldn't risk swapping parts that aren't made to the specifics of your engine

Your Intake and exhaust measurements (for both applications) are slightly off.
STOCK
5sfe= 32.5 intake
28 exhaust
2jz= 33.6 intake
29 exhaust

1mm gain if used.

They will work, but remember with any valve change you will need to do a 3-angle valve job. You would also need to correct the throats to make up for the new size. I just finished removing my valves, and measured them for you.


Also prepping the head for new valves, and high temp paint
(A bit Sloppy lol).
