Thank you for the feed back, 1stT. I have a metrology lab where I work - I'll bring in a denso Yzzf2, a Wix and NAPA pro-select and measure them. It will not include gasket crush, but Ill see whtas going on. I know the yzzf2 thread is very close to the gasket surface (may the data gods confirm my eyeball). -Bro
