? Valvetrain Geometry ?

First of all I want to say that this site and you guys are a treasure trove of information.

Is there any way to tell before you buy the roller rockers if they are appropiate for the application?

While I had planned on buying new pushrods, I had not concidered the possibility that the rockers sold as "for LA engines" would not be in the right place. I will be running Eddy heads and standard length valves. Ryan at Shady Dell will be doing the work, do you think he will be able to tell me which rockers will work?

Guys, I have taught my son that someones knowledge base is like a circle drawn on a piece of paper. Everything you know is contained within the circle. Everything you know that you don't know is the circle. And everything you dont know is outside the circle.

Thanks for making the circle bigger and showing me so much more I dont know.
