What do others use for head gasket material. I have an engine which I am having a problem getting to seal. I have tried .015 fibre gasket material and .030 material and also .33mm PTFE. The regular gasket material does not seal at all and the PTFE seals sometimes but not consistently. It may seal the first time but then never again. The design only has two head bolts and ath valves are off to one side in the head so not much sealing surface. Others have built this engine and have been successful. I have lapped the head and the cylinder on a flat plate with 1200 grit wet/dry sandpaper. So far no luck. The leak is significant.
