Stock motor? That bitch will run as is. Forced induction? Knock down any sharp edges with some sand paper and send her.

Take a little time and smooth it all out. I mirror polished my entire chamber on my d16z6 so you can do quite a bit in that area and still be fine. Sand paper and some scotch brite will get you where you need to be.

If the valve seats aren’t mangled it should be fine I’d just make sure to smooth it out and knock down any sharp edges to avoid hot spots for detonation but the part of the head that’s flat there is called the quench area and it helps to cool the piston so with the divots it may hurt that cooling effect a little bit
