im looking for ideas at what may have caused a few of my exhaust valve to just decide to bend, this is basically a brand new engine I put together and the machine shop rebuilt the heads and install the new springs for me. There is zero ptv contact, thank the car gods, timing is spot on, rockers and lash adjusters are in perfect shape so wtf could have caused his to happen? im thinking the machine shop messed something up when they rebuilt the heads but I want input before I start yelling at people.
In the pic the rocker is still on the lash adjuster it's just the stem is literally bent over to left and this pic wasn't even the worst example, on the other head the valve stem was bent completely in front of the rocker and the rocker was punching down on the retainer. Any input would help thanks.
