One of the last parts that I need to complete the engine. I was going to use the existing ones and change them out later if necessary. Being that everything else on the engine is new or redone, I figured it is best to complete the top with new assemblies. Postons has a complete set for $ 119.00. Are they good quality or junk? Let me know ASAP. It looks like I should have the engine installed by the end of January. Thanks. Len
