Agreed, and I have the tools to take the springs off and feel if the valves seem sticky in their guides and I can pour some solvent in the holes and see if they hold. And at that point call Speedmaster and then ask what the deal is?
My cam is only a 506 526 lift with .019 Lash with Hughes 1.6 to 1 rockers. I can't imagine the springs that are supposed to hold a 600 lift are going to be any problem even if I step it Up to a 573 lift which I was considering..
Thank you again for chiming in with your hands on experience with these heads. I am trying to create a spot here where someone can say they got a good experience or bad one from them.
