Did you install the O-rings in the head gasket holes? New o-rings, of
course. If so, could they have gotten displaced during assembly?

Recently did a Bayou 300, which is prob similar. (Except doesn't the
Lakota have a 4-valve head?)

The head gasket I bought was a simple piece of sheet steel, and called
for 4 O-rings, if I recall. The places where the o-rings went were
slightly indented around the holes. This made it so that the O-ring had
to go on one side, the side where the indent was. I think that the
head hole was indented, too, as I recall. It's been a couple of months.

Post some pix if you are not sure. You might also check if the oil
passages even go thru the head. Often they do not.

Look carefully at the new head gasket to see which side you put the
O-rings on. Also look closely at the head and jug. I do not recall if
O-rings are above or below.

As for copper head gaskets, I once had custom Cu gaskets on a custom turbo-ed V8. The material is soft, so it conforms to the head, and it is also sometimes thicker than sheet steel gaskets, which reduces compression pressure. I suppose copper gaskets would work better than steel if (in both cases) you left out the O-rings. Never tried that. O-rings are good.

Note that if you use thicker gaskets, you may mess up you cam timing.
