ahah... ok then.... Durometer is the measure of material hardness. this is not to be confused with a hardness tester.... durometers measure the hardness of soft things, that are often elastic or rubber, like a gasket. Maxwell hardness testers, measure the hardness of medal or other solid objects, like steel, and aluminum.
the conversion is easy its just multiplication and devision. it sounds like you used a faro to measure the runnout of the head. This tells me that your measurment given above was physicaly impossible. the standard tolerences witch a faro arm is capable of holding is around .0005 . this means that there is no way you could have measured the given varience with the tool that you used. no need for the picture, i get what your saying....
a quick sugestion that i might have, would be to measure the old gasket, compared to the new one. do a visual comparison, and see if the gaskets appear to be the same? is the head bowing down from the outside edges in? or up from the outside edges in? if its bowing down, its possible that you may fix this by simply tightening the head onto the jug. this will sench down, or flatten the bowing. understand?
anyways... i didnt take into account that your gasket could possibly be metal? if so, slap that bad boy on there, cause 15 thousandths crush should definatly be enough.... the standard i listed before was for felt/rubber gasket variences.... if it is felt or something else, then i do suggest you ask inspection if the have a "durometer". this will let you single in on exactly what thickness of gasket you need.
if it were me! id face the jug to match up! that way you will never have a prob!

ive never herd of a faro before either lol but im probably just readin the wrong thing they havent showed me how to use the machine properly yet and the inspector didnt say he just sed it was dead flat. i no what ur tlkin about with the durometer now doubt we have one because we mainly just machine the parts. my gaskets are both severly dead now they ripped apart when i got the head off!(ive tried it once already) i dont think the head is bowed anywhere it seems pretty flat i was just gunna skim it to clean it up as its rather scratched but i'll put a clock on it just to check again. but i know what u mean bout it flattening out. it has only got enough room for 1-2 thou' crush tho. for 15 thou' the gap i measured would had to of been .72mm. i was thinking about making a metal gasket for it what material would be best? if i skimmed the barrel to suit would i not get some major head slap from the piston or could i just take that up in base gaskets?
um? not sure what u should use.... i just inspect them... im not an engeneer. i do however have a bunch of engeneer friends, i will ask one of them what sort of material would be best for making a gasket.... i dont know about the head slap thing, an engine builder will need to jump in here and answer that question....

ah now i see what you mean thats a bit special haha i just wanna fix it i think i wld give up after a while if i was tryin to acheive a finish that would do that! also i cant get the two surfaces together without taking a MM off the top of the barrell which wld make my piston smash the head.
put a piece of solder in the cylinder with the head on and roll it over, this will smash the solder and tell you what clearence you are at, there will be a torence for that motor of how far the piston clearence is.. i take use silver spray paint on the gaskets to seal the zillas before a couple of good coats. tell mer what the motor is and i can go hunt for a gasket to.

ah cool mate. ive had a wee tinker with the head at work and ive closed the gap up to 1mm and got a nice finish on the surfaces so im gunna see if that squashes the gasket enough and makes a decent seal. and i think im gunna lower the compression a little wiv another base gasket on the barrell as it was pinking a little bit anyway. fingers crossed! cheers for all your help. ill let u no if it works
