Though I don't have flow numbers to back it up, I think the Al. L98 heads are almost infinitely better than the stock L03 heads. Be aware that you'll have to get a new intake because the L98's have different intake bolt angles than your stock heads. I've got flow numbers for the L98 heads on my site, if you're interested.

youll need to grind the center two bolt holes at a different angle to make it work but its a very simple modification

 

and yes those heads are wayyyyyy better than stock
