Quote: I'm using a Comp hydraulic roller(XR280HR-10), 440 source lifters, 440 source roller valve train and 440 source heads. No block machining necessary. So far, no problems.
I have 440 source heads as well. are you using all stock Stealth components with your combo, please? What type of Rockers are you using with that combo please? Thanks for all the good input guys!
