Just picked one of these up (correct part # according to their website) and in doing a dry a fit, I noticed that the diameter of the gasket (where the coolant/AF flows through) is smaller than the diameter of the outlet neck where it mounts to the block. As a result, part of the gasket rests on top of the thermostat. It's not going to block the AF/coolant flow released when the therm opens, but part of the gasket will be exposed inside the water neck outlet. My concern is the AF/coolant will disintegrate the exposed portion of the paper gasket over time and pieces of the gasket will end up in the AF/coolant and cause harm down the road. Should I be concerned about this or am I over-analyzing??
