Some other cooling hints are to remember to install the goofy
little scoop that scoops air from under the splash pan into
the radiator! And of course all the shrouds and stuff around
the fan.
I will see how my runs with its (even higher) compression
when I put it together. I know the water wetter works,
and that extra 5 degrees can help a lot.
Just my two cents on a Saturday MOrning.

Marc,
I run the other type with the centered spring and it makes no difference. I
run a 160 and it doesn't help as the cooling system is marginal on these
cars but I do believe that the design of the cooling passages in the block
and head are to blame also. Several heads I have have pitting around the
thermo housing due to cavitation. I spoke to a few people and showed them a
head and they said it was the design that caused the problems. Water/AF
doesn't like hitting walls and then traveling 90 degrees to get out. I got
one welded up and changed the angle a bit. We'll see if that helps.
If you removed that ugly valve then run with the heater cracked open a bit.
FWIW, the entire cooling system in my car is either new or in excellent
shape - the oldest part is the heater core and that has been flushed too. I
run a triple row 2L rad and a Spal 14" fan. I also use Waterwetter.
