cylinder heads cross ref

[rld machine]

I have a 1999 grand prix Gt 3.4 Ram air. I have one Cracked head. I Picked up a head from a friend that is good It is from a 2004 3.4. looks same does any one Know if any changes were made to these heads during these years ( will it fit and not have any performance issues?)
What is the best Gasket to go back with on the lower intake?

grand am, not prix. 2004 3400 has 8mm rocker arm bolts and 99 is 10mm so that will have to be addressed.

Felpro 980004T or something like that for the gasket. Its metal.
