quick question about porting

hey was going to get my barrel ported by someone but this other guy said he only ports 1 side of the barrel and leaves the other side not ported? he said you are ment to do that on air cooled barrels so it balances out or somthing? is that even true :wtf:

 

some guy ,who is he ,is he knowen for good porting ,have you seen any off his work ,to be honest sounds like a load off shit to me ,but i dont do the porting i pay people ,try some well knowen for porting not some back yard mate ov yours with a old rusty dermal

 

someone called craig used to work at a scooter shop, he us known for good porting he made that tiger runner blue and silver one someone owns on here
