so im picking up a 2003 2v gt from a friend of mine and its built for low boost everything inside forged blah blah blah but its a high comp. build 13.1. im a little confused about that but my question is how to i bring the com down to a boost friendly level without having to yank the whole motor apart? would a new set of heads maybe 4v heads and a thicker headgasket do the trick or am i screwed and have to take it apart? i wanna be able to run more than 6lbs lol
