I have a 460 in a 30’ Allegro class A Rv. It’s a restoration project. Insanity confirmed. The carb is a Ford/Holley E6JLAB, which I believe is a Holley 4180c. I have a kit which I purchased from mike’s that showed the Ford # along with the Holley #. My question is, will the Holley 125-500 check ball kit work in this carb? It isn’t listed by Holley but I have seen this kit suggested as power valve protection for the 4180c. This carb requires a 2 stage power valve. Thanks in advance, Gregg
