Hello,

I'm rebuilding a 1956 235, and I'm installing the new freeze plugs that came in my kit, and I have a question. I have an extra concave plug, which is the same size as the top plug on the back. I also have four threaded plugs that are about the same size as the oil galley plugs. Are they for an earlier model?

In all, I have installed four oil galley plugs, a huge plug behind the cam, another plug on the back, one on the front, and two under the intake/exhaust manifolds. Am I missing any?

Thanks, Vince
