Well I solved it by installing my TIS disc,
Everything is almost apart, only my E12 or E14 top didn´t fit in the head, so a buddy is coming to help out, also bringing his straightedge to check quickly if the head isn´t straight,
I marked the cams and the chain wheels to fit things back together, also marking the chain as well against the chain wheels so those things go corretly back together,
I´ll have pics up soon of the process
