Does a TUPY or Clearwater head use a better quality casting?

A Tupy head will be found in 2003 and 04 grand Cherokees and Wranglers and were made by a Brazilian company and it is a upgraded head. Clear Water heads are a brand new upgraded head shipped to your door for around 450$ Google Tupy 0331 heads as well as Clearwater heads.

Well I finally got around to working on the XJ and started with replacing the plugs. The plug tips were really bad. The gaps were worn to the point that the gap was probably double to triple the .035" spec'd gap. I did not do a compression check since time was not available to me. I figured since the plugs were so bad that I'd just replace them and see if I still get the cylinder misfire codes.
