If you deck, you can use a flat top piston, which is ligher than a tall dome piston, and allows better flow of the flame wave, and still have high compression numbers. I'm not sure, but I think they use flat top pistons in formula one.
Nope. Decking should only be used to bring the deck back to flat for a good seal of the gasket. Also, a properly made piston will not have a weight difference between domed or flat top shapes, and the domed piston would still have the power advantage because the compressed volume in the combustion chamber will be more even in thickness, which makes for a more predictable flame front in the cylinder, and also means that the force on the piston will be better directed to the center of the piston without the percussion effect of a flat-top. I would be thouroughly suprised to discover flat top pistons being used in formula one, considering all the engine manufacturing companies currently involved in the sport all use domed pistons in thier production engines.
