Tim-
I seem to recall that the later smaller port head actually ended up
makin mo' power than the big port model. You would be better off
changing the intake to the later style to match the head. The early
intake holes are pretty big for our agricultural revving motors!
The holes in my head are waay to big...

Subject: [FOT] 1.5 (Stromberg) head with 1.625 (S.U.) intake manifold
To make a long story short, I didn't check closely enough before I
had the
machine shop work done on a cylinder head and now realize I have 1.5
inch
intake ports on the head and 1.625 inch ports on the manifold. The
head is
for a vintage race car, 1961 TR-4.
Question: Is there enough stock in the head to allow me to bore the
head
intake ports out to 1.625 (1/16 th on a side) for a depth of about 1/4
inch
and then smoothing out the step with a die grinder? I just want to get
rid of
that abrupt 1/16 th inch step. Will probably wind up using the head on
a
Stromberg street car engine on my son's car in the future.
Next head that we do will definitely be a 1.625 (S.U.) head for the race
car!!
Thanks in advance,
Tim Murphy
