I don't have details regarding the extent of porting requiered for the DeLorean heads to gain the most power but you should remember that too much is worse than no porting at all. Velocity plays a key role in maximizing performance. Finding someone with porting experiance and a flow bench is the best approach. I doubt you'll find anyone with direct B27 or B28 experinace so it would be a trial and error technic going a little at a time.
