I am not sure.
I know that the heads were designed by Yamaha (as is the 4A-GE heads, and others) and that not many parts are interchangeable. Different intake bolt patterns, exhaust, nearly every piece was changed despite it still being a 3rd generation VZ block.
I have a friend who tried putting the FE heads on the Hilux 3VZ. I do not know how many complications there were/were not, but I do know that since the Camry engine was transversely mounted (FF), the distributor is on the right-side of the engine as well as the throttle body. What that means if you try to swap it into a Hilux (FR configuration), not only will the distributor interfer with the firewall, but also the Throttle Body is pointing at the firewall. So modifications to the intake manifold plenum and also relocating the distributor to run off of the front cam gear (direct like on a 20-valve 4A-GE, and others) will definitely be required to run the Camry engine in a Hilux.
