I have a 96 Xplorer 300 with a few performance modifications. And I was wondering if you could run 93 octane premium mixed 32:1 if i got my head machined for higher compression. If I could, it would only cost 60 bucks plus shipping. And that's cool!

 

That is correct . The head can be machined to use 93 octane with no problems .

 

I use 92 premium and mine does just fine.
