317 heads, if you zoom in you can see the sand paper roll ports, nothing too aggressive but just smoothening the intakes and valves to get rid of the casting marks

if you zoom in on the exhaust ports you'll see they've been sand papered rolled, just to smooth out the touch casting finish

Thanks for some updates, it's nice to see someone making progress. I got my heads and block (with rotating assembly balanced and installed) back from the machine shop a couple months ago. They've been sitting in my garage, bagged up, since then waiting patiently for me to get back to them.
