Here's (probably a stupid) question for you. I have a set of GT40 heads for my 302 (formerly your 302) and they have 7/16 rocker studs. That would completely negate being able to use stock type rockers and rocker nuts, I would imagine, so I would need to buy the rockers and the (god forsaken) Poly locks. I'm planning to run a hydraulic cam, nothing radical because I need a flat torque curve for the autocross. Any recommendations?
