the problem valve - Theory

[ilya]

a situation that in the spring I will be more firmly engaged in the machine, I already have VTEC HEAD. then I'll change it, change the Timing belt, and so on ...
There are many reports of improper installation and the rest of the Timing belt. Timing belt are sometimes installed in service. the problem is that the valves are bent, broken. what is the problem?
I see all this for the first time, I will certainly do the instruction book but may have features? stretch belt?
