Default Cylinder heads

Hey all!
I'm thinking of doing the 2.5 to 3.0 swap in my '95. Looks like a pretty simple swap. But....do i have to change the whole engine or can I fit the 2.5 heads to a 3.0 short block? What are the barriers? I have a 3.0 laying around already from a dodge mini-van but it has the SOHC 2 valves per cylinder heads on it. If the blocks are essentially the same, can I just bolt on the 2.5 heads with the 4 valves per cylinder?

The 3.0 swap is only the listed cars in the write up the 3.0 from the mini vans do not fit and can't be adapted to the heads

Thanks bad venge. After a bit of trolling around some other sites, it seems that the heads on the 2.5 and the 3.0 are identical. 'ppreciate the responses...
