Never bothered checking how they were set up from SM. I removed them and installed something else. The only specs I know of are what I posted from SM.

I have them checked on my heads and the specs were very close if not spot on. I'd have to look...

I'll take them if Garrett doesn't, or I'll give you 55.00 and nobody has to know anything.
