Subject: Overheating problems
>I am just about out of ideas. The car runs well but still overheats,

>and my head thickness is 3.240" (yes, that's correct).

>I am not getting excessive bubbling in my coolant this time thankfully.
> The car just creeps up in temp until it hits around 210, WAY too high.
> I bought a new 180 thermostat, then removed it and ran with no

>Any thoughts on what else would cause it to overheat??? The timing is
