Valve stuck again...

That pattern looks a little wide IMO, like the shaft needs to be shimmed a hair higher.
Whats the cam lift and the coil bind on the springs?
Seat and open pressure?
What wall thickness pushrods?
I'd also check seat runout if they did a valve job. Most shops don't do that either and the seat will **** the valve head and bend it and beat the crap out of the seat.
I run my guides tight- but their straight- and I don't have any issues with valves sticking or taking the springs off of seals. I see lots of shops use HSS reamers or just broach a guide and the guides aren't straight. So they ream or hone them bigger until the valve goes thru and now you have guides that wear out in 1k miles, the plugs get loaded with oil and it becomes a fog machine because in order to get the valve to fit they make it too big.
