Dont really no the diff but you would certainly want them to match all of the other engine componets.
I had some head work done to my '06 by a local builder.All I know is the heads were worked to match everything else or visa versa.

 

The one thing I do know about them is the pistons need to match the heads and the bore needs to match the pistons. As for all three of those heads I posted will work with a 96 bored to 103, but the rest im lost what the difference is between them ....

 

I see 3 different heads listed, with the valve sizes getting progressivley bigger.

I don't know what you are building, but it better be an monster if you go with anything bigger than the valves in Heads #1
