so i have a set of valves and retainers i bought. they are brand new out of box. im told they are supertech. but im not positive. so here are a couple pictures. if anyone has any idea what brand they are please let me know

 

i don't believe there supertech's because the intake valves have no second angle cut to help with flow and they are not back cut. most supertech's these days come nitrate coated to

 

Def call the manufacturer and make sure?

 

a local shop told me he thinks they are rev brand. i bought them open box new from a friend of mine. he said they were supertechs. idk.

i was looking around they look similar to manley and brian crowers??
