Hey guys I am not going to do it myself, but since the head gasket need replace i minus do it right now when pulling the cyc head. Going to get it clean and check for crack but when I do bring in my head what kind of mod can I add to the job? I know port and polish, valve job, large valve increase, and shave head. Sorry new to this and couldn't find a nothing in search. Don't want to bring it end and not know what option are also there for me to do. Thanks guys.
