   Basicaly im getting another head from a 01 vtr same as mine.. and going to fully rebuild it and go for 285's instead off 270's, but is it possable for the head to be sent off and have larger vavles put in?
   
   seen it done on a Xsi head but not on a vtr yet, please no just 16v as theres no way im going to.
   
   Also im gunna be running a GMC 1.9mm headgasket to lower the compression as ill be turboing nearer to x-mas, but will it run fine with the compression plate on?
   
   cheers.
