99+ also have different intake and camshafts to go with the PI heads. I believe you actually end up with a little more hp than a 99+ when you do the swap because you end up with slightly higher compression. Do a search of previous posts - there are some folks on here who have done the swap and who know where to get the parts for the best price.

THE 99+ HEADS HAVE MORE AIR FLOW THAN THE 98 AND BELOW.
