The reason its angled the way it is is so when the spark plug fires the flame front does not rock the piston from front to back, it aims it parallel to the wrist pin so there is no rock in the piston. No one wants the piston to rock back and forth at 8k rpms do they??

Generally piston rock is dealt with more so by the pin location being offset on the piston itself no???
