I have never pulled the inner spring for breakin and never had a problem. I use Joe Gibbs breakin lube, grease on the cam and on the lifters when assembled. It stays in place and wont drip off. Everything is set up when started so it fires and goes right to 2500 or more RPM then I set it down to 2300-2500 RPM and leave it there.
My process exactly, down to the brand of oil! except this one sat for 3 years! not the 2 years I originally posted LOL. It was likely a combination of factors I needed to hear from experienced people to help figure it out.
