Valve melted to the valve seat. Taking my injectors to be flow tested/ cleaned at RavenWorks. Any other reasons it could have burnt like that? Head has around 152K and is all stock

Just dropped the head off at Gosh. Going to be cleaning up the bay a little bit. Next is to drop the injectors off to be flow tested. Will also need to remove the flapper for my new external wastegate and o2 housing.

If the injectors test out fine what else could be a cause? Trying to eliminate all the possibilities that could have caused a burnt valve.
Mark and I discovered that the chunk of my missing valve had melted to my valve seat. I tried to get a pic but my phone isn't the best up close.

Lots of buildup on the valves too from the looks of it. That can cause hotspots, but I haven't seen it like that before. I wouldn't get too worried about it, just replace it and put it back together and hope for no turbine damage.

Turbo is perfect. Took it all apart last night cause I was nervous that a chunk had to of fallen into it, but nope! Still a little hesitant but all checked out.
Waiting to hear from Gosh to see if I need new seats (which i'm positive I will) and if they had any valve seals in stock cause I couldn't find mine in time. Then taking my injectors in on Friday morning.
Hoping everything goes as planned.

Finally got the pic of the valve seat I sent myself.

This is where the crank lined up to the timing mark when the cams with lined up and at TDC. How does it look?

I'm no expert here but it looks like the crank trigger is a tooth off.

That's what I was thinking. Want to get it perfect when I put the belt back on.
