ls9 head gasket
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
put some ls6 valve springs on, they have very low miles, they got put in the jet washed so thats why they aren't super pretty

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
about to check for pushrod length
new valve stem seals
lapped the new valves in, pouring a small mount of oil into the valve stem guide
another shot of valve stem seals

new knock sensors
just another shot before it gets dressed up
about to torque the head down, using GM performance brand head bolts
knock sensor harness
couple of hardware issues, <br/><br/>like the throttle body bolts being way too long,... almost like theres supposed to be a throttle body spacer, <br/><br/>and two bolts that hold the fuel rail down, didn't come in with the box ...

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.
