Has any tried one of these? How was performance affected if at all? >>
Bruce,
I recently purchased and installed a Moss ally non crossflow head when I
rebuilt my 1976 18V engine this summer. It went on easily..I have found it to
be a good part..My mid range power is up a bit(less squish area in the
combustion chamber-valve area?)...It sealed well using 60 ft.lbs. of torque on
the head bolts..Carb and exhaust port areas are well surfaced..the ports
themselves are smooth and a bit larger than the cast iron equilivents.. I am
pleased with the head..I had my machine shop fit a new set of valves and
springs and went driving..It has only 3500 miles on it now, but seems to be
doing what it is supposed to...and it looks good sitting atop the iron block..
Yours,H4(Howard)
