Problem solved My ignition was too advanced. After i set it to 1mm btdc it stopped blowing inner headgasket

My gas gas ec 125 has blown about 3 head gaskets. I have had 2 cylinders and 2 heads , and it has blown the gasket with both. Gasket surfaces are straight and this has happened after full engine rebuild . What could be the problem?
