Will 4.6 bolt into 4.0?

Will 4.6 bolt into 4.0?
So, I have had some issues with the engine... it is getting close to the time to either rebuild or replace the engine I have found a 2003 4.6 that someone is willing to sell for 350.00 it is complete with all the auxiliary parts. The heads need to be done (not an issue for me). But I am wondering IF the 4.6 will bolt right into place? Appreciate any help / advice.
Cheers!

You are right... it is an SAI, but I do have a set of 4.0 non-SAI heads. Question is will these heads work on the 4.6 engine?

That looks like a clean engine for $350; hope the internals are good. The oil filter is an OEM LR unit which may be a sign of proper maintenance by the PO. Good luck with the swap.

Yes, confirming the heads are interchangeable. Only thing to be aware of is using SAI heads on a non-SAI vehicle you have to thread plugs into the SAI ports on each head.

Also, the stock 2003 sai heads that I swapped on were very soft. The threads stripped in several places at recommended torque and I had to helicoil them. That was probably specific to those heads.
