<VV> Oil and head temp correlation

[Stephen Upham]

Could someone tell me if there should be a correlation between the  
head temps and oil temps or not.  I observed very high oil temps but  
normal head temps.  The oil temp, measured with an adapted water temp  
gauge with the sender just above the rim of the oil pan in the block  
was reading 270 (gauge goes to 280).  Normally this reading was in  
the 260's at the highest.  I measured the temps with a laser  
temperature devise and the oil cooler was at 200-205 and the oil pan  
was 240.  The dual CHT never got above 250 and was steady throughout  
the time that this was happening.  This has been a pretty normal  
reading since they were installed when the engine was rebuilt two  
years ago.  I'm also wondering if the oil in the car has been  
stressed and should be replaced.  I'm using Brad Penn racing oil (the  
green oil) and it has only been about 250 miles since the last oil  
change.  I have been using this as the break-in oil before switching  
to synthetic.  I WILL be dropping the shrouds.  I had kept them on  
because it was taking forever to get the engine to 220 in order to  
prevent acid in the oil.  I now prefer to drive for a long time at  
each outing than drive for a few miles and replace an engine.  I  
recently bought a gauge that I can install in the port of the Clark's  
ultimate oil pan that is on the car.  I hope to do this with the  
other gauge still installed for a while to compare temps and see how  
it compares.
