<VV> Heads too hot

[jvhroberts at aol.com]

 1. Check your gauge. Given how low your oil temp is, I find it hard to believe the CHT is actually that high. Check the connections, make sure you're getting 12 or more volts at the gage, make sure there's no bad grounds, etc. 
2. Check for pinging. If it's not, you're also probably not running that hot. 

Which engine are you using?

Basically, sounds like the engine's fine, the gauge is suspect.

Hi Folks,

 

I have a problem that i just can't get solved. I rebuilt the engine of my
'64 vert two years ago and about everything is new, based on one of the
major rebuilt kits of Corvair Underground. I installed a Spyder dash to keep
in contact with the engine. Now my oil temp is running fine at 180 F
(external oil cooler above the fan), but the heads are between 470 and 500 F
after a 20 minute drive. It's not running lean (check), static timing is
correct on 14 degrees (check), I use the right spark plugs (Delco R44F,
check), I just deflashed and cleaned the heads (check),  lower shrouds are
off, weather temp between 55 and 70 degrees Fahrenheit.  Any Ideas?
