82 big red, needs rebuilt now what next?

So I took my big red to the local small motor guy who rebuilds all my junk.

This time he said my 82 big red needs rebuilt.

could be rings or ???

It burns out the spark plug coating it in oil now and also smokes oil out the exhaust.

What kit or rebuild kit do I buy? What is involved with a perfectly working big red motor that will make it gum up the plug every time?

This is the 3rd carb rebuild we did so we are pretty sure its the rings or motor parts?

Im not very smart and the mechanic said "buy the gaskets and rings" but could it be the cylinder head costing much more $$$ making it not worth it? :rating06: :stupid: :icon_ banned:
