im installing a ctr cams on a gsr.... thinking of using stock itr valve springs.. what else is needed to complete this swap??

 

I don't think anything else is really necessary, but it is a good idea to go with the ITR LMA's and maybe ITR retainers (if there is any difference). The lighter ITR valves are also a good thing to upgrade, but still not necessary.

 

im not upgrading any of the valves.. im just dropping in CTR cams and stock itr springs.. just wanted to know what else is neccessary... thanks
