I am sure the valve seating surface can wear along with the valve seats in the heads. Take them to a shop and have a good valve job done and he'll be safe.

 

Yes.Valves and their seats wear after time.Depending on heat,mileage,fuel quality,general tune of the car,RPM's and spring tension.This is why it's common to have the valves cut when you do a head job.

 

Sean, looks like you'll need to do more than just get them dipped.

 

lol awesome....so i took apart one set of heads and all the E and I valves are out....should i put them back in and have the machine shop look at them and see what needs to be done? the shaft of them look fine....its the underbody of each valve that looks like crap....do i also need new valve guides?

 

Wait, Sean are you seriously selling that auto tranny for $25 picked up?!? LOL!!

 

^dude no one wants it.....ive had it for sale for $50 forever...why u want it? lol

i might just part it out and then ship the pieces....

 

The deal is if you have the valves out of the heads at the very least they need to be marked and go back into the same place as the seats/valves wear in together.This is why it's just easier to break them down and have a valve job done.
