Hey guys, lately my valvetrain has been a little louder than normal so I think its time for a valve adjustment. I was wondering, with my supertech valvetrain, if the specs should be different than a normal stock head. What specs to you guys normally run with aftermarket valvetrain? Also, running stock GSR cams.

 

Run stock lash, for a stock cam.

.006"-.007" cold intake

.007"-.008" cold exhaust

Doesn't make sense to me that your running aftermarket springs with a stock cam...

 

cams won't be stock for long.
