If you get a whole 6A/9A don't bother taking the head of if it's in good nick, will just cost you a headgasket and bolts, whack in the KR inlet cam though the 9A is too flat. Best option is a good 2L bottom end (any 16v engine code) plus a flowed head, all the 16v heads have the same potential flowed. Quote Share this post Link to post Share on other sites
