so a friend of mine got a K24 complete cause he wanted the bottom end and he has no use for the head. As far as I know, its basically an A3 head only with bigger ports & valves to accomodate the additional displacement. If it were to be sold, it would be completely gone over by a machine shop to verify its condition just to be sure. Also, the guys at the machine shop are friends of mine & they'll do porting work for me pretty cheap so I could have that done also. Anyone?
