greeting,
I installed the alloy head on my 1976 B roadster
just prior to a planned 30000 mile trip around the USA
in 1998. I installed the head, a weberDGV carb and as
ansi exhaust, along with a 1974 overdrive tranny. My
trip started in Ft.Collins, Co in early May. I drove
the B all over the country, crusing in the 75 to 80
MPH range. I endured temps of over 110 degrees, and
maintained an engine temp of 185 degrees. I feel that
if I had my iron head on this car, it would have
suffered a bit more.
The DGV carb behaved as well as I could have
hoped for. Fuel milage for the trip averaged 26 MPG on
mid grade fuel(89 octane). I still have the iron head,
on the shelf, in the shop. I am saying that the alloy
head actually ran better than the iron head..just my
$.02 worth.
