Lifter pump across different rockers/pushrods is a different thread all together.....

I do not have the tools/time to do the research that needs to be done in the lifter area, but I have ran many different types of lifters to have some general idea of what happens....

Long story short, lighter rockers have more tendency to float valves due to lifter issues.
