where are you riding this thing?
wonder if your riding on the street most of the time if people would still advise shocks and a arms when people want to go fast.
maybe you could use .030" base gaskets and then check port timming.
copper spray on the headgaseket might work or at that point you can cut the head flat so it will seal properly
with a squish that tight and looks like the band is huge, I would want different domes anyways... next your going to be blowing out fire orings
save yourself the trouble and do what you know you should do, call noss machine
