Here's the business end of things. First of all let's offset the ring gaps, then we'll use these hose clamps for ring compressors, and some dowel rod pieces to support and protect piston skirts from getting banged by cylinder studs. Notice the lifter oil hole i am pointing to on tappet, this must align with oil feed hole that is inside exhaust lifter base "VERY IMPORTANT". Orings are used to retain lifters in bases. Cylinder and lifter blocks and lifters are all in place now. Base nuts installed.
