In a word yes will work, I've done it. I think the 5.0 doesn't have quite a small much advance and I suspect you have no knock sensor on the 5.0 module. Verify that youre getting like 26 degrees advance all in and it should work.

without knock sensors it will work. 2 more degrees of advance, however not enough to worry about

if you had knock sensors, then it wouldnt work as the knock tuning would be off.
