Stripped header holes, need advice

[Bill Glaze]

I've used them (Heli-Coils) on full size engines and they are commonly 
used in spark plug holes in aluminum cylinder heads, and as repairs on 
cast iron pieces.  Work fine; I do believe I just may get one or 2 sets 
for use on smaller sizes that we use in modeling.  Never used one 
smaller than 1/4-20 before, but I see no reason that they shouldn't be 
as good.  Anyone ever used  Keen-Serts?  (One piece thread inserts.)  
They work well also, in the larger sizes.
