Timing question

[fixkick]

now how end this in future?
we dont do that here.
IF a head warps over say , 0015" then its oven heated to relax said warp
all head shops USA (aluminum) do that and then measure warp again. (may go to oven again... yes skills max here)
then shave it LAST, if at ALL max 1 to 2 thou max. in fact its what is called a clean up cut, to get max gasket seal. only

even less.
this is so you dont get where you are now.
and all heads the are warped and not OVEN relaxed fail.
all fail soon again, all do (the usa authority on heads, rebuiders pages and ASE.org , list this as top cause. of later failures
this is a prevention post ,not cure.
