lakota300 topend problem
#4
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.

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.
