2V 5.4 VS 4.6 2V heads

Any difference? Do the truck 2v heads have bigger valves/ports than the PI 4.6 head? I know they are interchangable, would 5.4 2V heads be a better choice to begin porting with? I'm still exploring head frustration issue.

What he said....same exact heads... if you are still looking for heads, try to find late 03 or 04 2V heads. They have more threads in the spark plug well and will help prevent blow out.
