Eddy head question

70aarcuda, you have been a huge help. I was almost considering returning em cause it seems like so many people kinda have horror stories on them, and the added expense it started to sound like i was gonna have to spend, but I'm gonna go start putting them on tonight. Unfortunately I can't afford having a machine shop go through em so i am gonna just inspect them the best I can, and remove the springs to check to make sure the valve guides aren't to tight against the valve, and just take edelbrocks word on them being a true "bolt on and go" and hope I don't have any issues. Is that what you did? just take em out of the box and bolt em on? Thanks again for all the help. -Kory
