Another consideration, those are not self aligning rocker arms, you will also need to install studs for the rockers and guide plates for the push rods if your heads don't have them. Your stock rockers use a fulcrum for a pivot instead of a ball which also keeps the rocker arms and pushrods in alignment. Your rockers show some wear, if the engine were mine I would replace the stock rockers with new OEM style rockers made for your engine and spend the money on something that would actually improve the build. Did your machine shop check the cylinders for size and roundness? Stock blocks with some mileage tend to have a cylinder or two that are egg shaped a few thousandths which will have an adverse effect on ring seating. How much are they planning to hone the block, and what will your piston to wall clearance be when the block is honed?
