Valve stuck again...

I dont know if anyone remembers my other thread, but this is the third time this has happened to me. First two times were RHS heads and they didnt even last 10 min before sticking a valve. This set is EQ, ported with 2.02in/1.60ex. I have about 1000 miles on this combo. I have included some pics, i can only figure out one pic at a time on my phone so bear with me. Any input at all on why this is happeneing is GREATLY appreciated. Im getting really sick of changing heads with cheapo headers and power steering :banghead:
