yes .. for the 2nd time I'll have again this set carefully cleaned and reassembled to be sure they go inside the holes better than new out box.
Anyway tomorrow I'll take heads to machine shop to see what we can do to get the installed spring height as close as possible to 1.900 recomm value.
actually these vintage DC stage IV heads, ported and cut more time in their life have some valves quite recessed expecially intake ( dont know why) and even worse the stems were cutted to balance .. ( these jobs belong to the past of this car) so will update how it ends more ahead. thanks
