I have been offered a complete sti 4 engine and would like to know the difference between the heads, and how much affect it will have on performance as the car was mapped on a power fc with v3 engine.

I thought the heads were the same but the V3 had a slightly wilder cam profile.

yeah shouldn't be a problem.
Your fuel pressure reg is held on with the hex head screws so comes undone reasonably easy..
