will the part fit

hello, new to this forum.
can anyone tell me if i can bolt on a set of cylinders and pistons from a 2010 ultra onto my 99 road glide ?? what are the differences ??

 

Nope, the stroke is different between the 88 and 96 engines, hence cyl. height.

 

If he had said cylinders and "pistons with rods" notwithstanding
the valve train, heads etc, would it be the same answer?
