just checking in with members who use the Mopar Stage VI heads.
have you had any issues with the valve stem design how the spring seems to be floating in oil & the valve stem seal has to be perfect or it leaks down the stem & gets sucked into the intake?
i've had a few sets of Indy heads but i now have a set of Stage VI's that came on an engine i bought. i had an issue with the RH bank smoking a bit & traced to the valve stem seals had come loose which allowed oil to leak down the intake valve stem.
to fix it i got creative with the die grinder & reshaped the area around the valve spring seats so the oil could escape quicker. has anybody else done this? i'm kinda at a loss to understand why someone would design a head like this, but i'm sure what i've done will reduce the chances of a recurring failure. also everytime i removed the valve cover, oil would instantly dribble down onto the headers, what were they thinking?
they started looking like this...
