Ported 241's vs...
#2
depends on the porter this is a herated discussion use the seach tool and u will find at least 20 relys to posts just like this 1 . for the cost to have your heads hot tanked, ported and polished you will see similar gains to buying the 243's just while you are in there replace your intake and exhaust valves for some beefier ones and you will outperform the 243's all day
