what type of valves do i have

[nofx230]

i noticed when i had my head off my car that my valves don't have 7M stamped on them? my question is did all 7m motors have the 7M stamped on the valves? and if not how do i know what valves i have in my motor??

My OEM valves had 7M cast into them, so I'd guess they're stockers.

the valves in this head don't have 7M on them though just wondering if theres and distinctive marks on aftermarket valves or the way they are shaped that would let me know what type they are

For some reason I thought in one of my heads they didn't have them. They could be stock. Most likely. You could measure them tho.

they may be oem style replacement.. we replace valves at work all the time with oem style valves that are unmarked

Are they clean? Usually that cavity gets filled with carbon.

the exhaust valves have a lil dimple in them and the intakes are completely flat on the face
