As far as I know bb mopar gaskets are reversible. So you can't really install them upside-down. Some engines have a front and back way to install them like a Ford FE.
Timing certainly could affect the engine temp. Is this a quick fuel 450cfm on a big block???
Thermostat quality isn't the best these days either. It could be going bad and just a coincidence that the issues showed up at the same time. Probably unlikely so..but we often over think issues. At least I do all the time.Lol

HI,
Mine is a SB. 318 Thermostat is/was new but was a cheap brand. Maybe I should change that to a Stant.. Are the Head gaskets reversible on the Small blocks? I think I looked at them and FIRC they looked the same on both halfs of a gasket. I think I have the old gaskets I'll look

318 gaskets aren't reversible. Here is a image of a felpro.
