Thanks for the replies, I was planning on checking the valve to piston clearance. I need to order my cam, lifters and push rods. To check the clearance I need to order a solid roller lifter in place of my hyd roller lifter right? If pistons do need to be flycut do I just mark them and take them to my machine shop or bust out the dremmel. Been a while since I built a motor and my usual machine shop closed so I will be using a new one I have never tried.
