Ceramic coatings.
Has anyone tried the Tech-line coatings or Cerakote?
I am currently building a 350 that came out of an 85 vette (not for my chevelle, that is a 454) and the heads are prone to cracking. Both advertise that they are "thermal barriers". Would this help with cracking problems?
I would just get Trick-Flow heads, but that takes money away from the Chevelle build.
