Pretty sure EJ255 & 257 blocks are the same, the heads is where the difference is (WRX vs STI). Someone correct me if I'm wrong.
As TJ said, get heads done locally. The more aggressive the cams the more power you can make but you will sacrifice driveability and have a nice lumpy idle. Suss out the actual specs of the cams and work out what you want. Cosworth 272s are less aggressive and have a shorter lift then say Tomei or JUN 272s.

EJ255 has less bore webbing than the EJ257 asfaik... if u want to make bulk power needs to be close decked and sleeved... id be shitting myself without one.. as well as id want big fk off headstuds.. Cams you want a much higher duration, im running 272/2?? cant remember but i should have gone for some kelfords with a more aggressive cam but im making enough power to not worry about an extra 30-40whp..
