does anyone know the k20z3 head stamping codes? or all of the head stamping codes? Thanks

 

is there a different code used on k series heads, i believe a k20a motor has a k20a head and all its internals, a k20z3 motor has a k20z3 head and all its internals as well, i know there is some variance with each head but their shouldnt be a completely different code like you see with trannys:motor ... sorry i cant help you

 

wow, seems like most (or all) of your posts are just pure nonsense. spend more time reading here and less time posting. the head code IS NOT k20z3, i can promise you that. that's the block code.

 

LOL he's like the guy that points out the obvious in pootytang ahhaha

 

Should be either an RBC or an RRB based on the part numbers. I've never checked one for certain.
