Some SB2 info:

http://www.derrikecope.com/wcup/98/sb2.htm

Pertinent to this thread:

"The biggest differences are in the port layout, valve angle and combustion chamber design. The only things that remain the same are the crankshaft, rods, oil pan and water pump. Other than that, everything has to be changed to accommodate the new cylinder head."

This means the pistons are also specific to the SB2 head/block combo.

Things have changed a little since 1998.

Cup teams can't release part's newer than five years, so anything you buy is at least five year old tech.
