Hey guys, I recently had new valve seals insalled for the second time on my LS head and it still keeps smoking when I stay on a low gear during a downhill or downshift abruptly (high vacuum) and then resume acelerating.
I also hear a metalic ticking noise coming from the exhaust side of the head.

Could this be a bent valve or a damaged valve guide or what??

TIA
