Hi Experts, looking for a educated opin,on how bad is this gouge I was thinking I could radius these little gouge without major reboring but would that effect the timing? Any input valued . Thanks, Paul

Kind of hard to see the pictures but doesn't look like anything major. Looks like it's only affecting 1 hole? Probably no affect on port timing.

I usually put a small radius on all of the sharp edges on the ports where the piston/rings ride to minimize the chances of catching a ring and breaking it

Thanks for the reply, yes, just one hole is the first image loading? it wasn't for me. That's good news i would say about say .125 radius would be what I need maybe little less what do you recomend?. Regards, Paul
