Hey psa. What do you think this noise could be? Sounds valvetrainish to me but not sure. Only seems to be hot and at higher idle. Backround on it is has ford enhanced (4000 miles on it)shortblock, elite pushrods, springs,valves(carry over approx 20k on those), and rockers were installed at time of shortblock. I'm thinking maybe a couple of valve bridges are wore more then I thought.
