The 904 kit increases displacement enough to provide more room in the cylinder for bigger valves which opens this motor up to higher Tq numbers at lower RPMs




I wonder how much bigger valves really would add IRL. I've got >57 lb ft out of my 904 with the OEM "small" ones. I honestly doubt (but I could be wrong) they would make so much difference. And when you think of the cost involved...
