110 to 117 head work question.

I’m looking to have my heads done before having my 117 kit installed . I’m looking for opinions on what I should have done and who you guys recommend to do the work. I don’t know anything about head work so please feel free to educate and give opinions.

thanks guys .

Plenty of options, you have to frame your expectations and desired outcome, do your research. Read posts on this page from Hillside and Prodrag1320
