My opinion is exactly what I posted in your other thread
. Bent valve will run fine if it's not bad. It'll also build compression.
Your main concern is finding it, if you over rev once and bend them enough to not sit flat on the seats, but run, it's very bad. What happens is everytime it hits the seat it bends back for a split second. All that bending back and forth will eventually break a head off one.
I know, I did it once, I over revved and it ran kind of funny but I got over 500 more miles out of it before an intake valve head broke off. Ruined the head, piston, rod, valve train, cracked the cylinder.
All the other cylinders had over 100 psi but the machine shop said the valves were all bent.
What exactly do you want an opinion on?
