I had this problem with my old motor, have you checked to see if the head is tight down correctly and evenly?
If you have and that doesn't fix the problem try the paper gaskets and some gasket glue/sealant. If you use this method make sure to follow the instructions for "Setting time" because if you don't it will be a waste of time
Hope that helps, good luck

paper gasket material will not hold up under the heat.
you need to get a new steel or aluminum head gasket (not sure what they're made of), and put some copper rtv sealant on both sides of the gasket before you put it on.
you only need a thin layer of the copper rtv, just enough to cover the surfaces of the gasket.

RTV on a head gasket is really unnecessary, it's not going to last with the heat and metal gaskets. A metal to metal to metal bead at 15 ft/lbs w/grade 8 steel head bolts is plenty.

head gasket and torc
On my little engine I only torc my head bolts to 12 foot pounds and it seems to work OK. I need to check the head bolts once a week and they do seem to loosen up after awhile.
All of the head gaskets I have dealt with are aluminum. I got a thinner one than stock in order to rase the compression a bit, but I am not sure weather it makes any difference.
I don't know if getting better main bolts will really help but I am sure that it can't hurt. On my first engine the manual said to torc them to 15 pounds and at that level I striped a nut.(cheep boy go slow parts) I thought it was a bolt and replaced what I thought was the offending part only to find out it was the nut.(sheepish grin)
I have on all of the other hardware have upgraded with the Sick bike part kit and tried to double nut all of my fasteners.
So far so good and I have about seven hours on my new engine(I installed a tiny tack with the new build) and knock on wood it won't blow up unexpectedly, But who knows. Things usually fail at their weakest point and if you want to keep it prefect don't ever take it out of the box, then in a hundred years it might be seen on the Antique Roadshow. Something I have .serous droughts if you wile be there to get the glory for saving this strange little conveyance that has fortunately slipped in between the the cracks of our legal system.
