Exhaust manifolds

[JOEHOLSOM@xxxxxxx]

I am getting ready to replace the cracked exhaust manifolds on my 65 
convert.My mechanic says that we have to have gaskets or the manifolds will 
leak and I will have problems down the road. The field service service manual 
does not show the use of any gaskets. I guess what I need to know is which 
one to follow, the manual or the mechanic? Thanks,
