round head vs square head

[yayo65]

hi everybody, i just searched for similar topics but i havent found anything.

maybe its a very silly and common question, but i just wanna now which 48 cc engine is better, the square head or round head? and why?

thanks!

I've been around a bunch of these and find that the round head will out perform the square head every time that I've known about it.
