Never thought of doing the 'lift the corner' thing, neat idea. I think, though, that with the bypass hose big blocks don't usually need it. At least I've only had air trapped in small blocks. I like the old 90s LT1 with the bleeder valve. Probably because they were prone to it do to reverse cooling, but it made things pretty simple.

Maybe I should invent the "thermostat housing with integral bleeder valve" :-)
