You will need to sift through all this to weed out the redundancy etc but I found most of these from GNTTYPE.ORG. I had posted my info here (as did others) before the crash so archives on tbuick are gone.
If you need this in a spreadsheet lemme know as I doubt the formating will hold - Shawn
Mine, then the others:
Heads have little portwork as most of the modification was in the bowl area, but even then these are not "worked" heads since more could be done.
For some readings I plugged in identical values even though it may not have been actually tested… the reason for this is that there was no gain for those data points.
Example: the exhaust flow did not gain above 0.400 lift.... the porter had just drawn a line through the rest of the range

From: Barry M Goldberg
Can someone comment on the flow numbers that were done on the heads I just
recieved. I don't know how this is compared to a stock head. When I look at
them there is no comparison to my trick flow heads that I had done on my F--d.
.100 59.2
.200 127
.300 175
.400 193.2
.500 201.6
avg intake 174.2/1.775 manley valve
.100 49
.200 98
.300 142
.400 154
.500 156.4
avg exhaust 137.6 /1.50 manley valve
Thanks

Hi Mike:
Intake tested @ 25 inches water:
LIFT: FLOW: Same except @ 28" H2O:
.200 113 120
.300 163 173
.400 190 201
.500 196 208
.600 202 214
.700 206 218
Exhaust: As a % of intake:
.200 93 99 82%
.300 129 137 79%
.400 142 151 75%
.500 143 152 73% -- Don't know why
.600 143 152 71% -- these last 3 entries are
.700 143 152 69% -- different %'s
After about .400 lift, on the both the Intake and Exhaust, there doesn't seem
to be much gain in flow.
These are stock 1986 TR heads that had a full port job: intake ports, bowl,
exhaust ports, and 1.77" Intake valves.
HTH,
STEVE

Ive included a copy of our ported Iron heads flow numbers
Take note intake flow numbers are similar,but our exh. out
flows theirs.

Hi All,
I just took 2 heads to the shop and had them flowed. One set was a
Champion
"out of the box" and one set we ported and back cut the valves. I know
all
flow benches differ but I was somewhat surprised at the results.

Intake and exhaust were both ported substantially with the original
valves
being used, the intake port is more than adequate for most applications
as it
is fairly efficient out of the box while the exhaust needs improvement I
feel
that a larger intake valve is needed to flow more at this point(probably
not
needed for most) as we made the intake port pretty much as efficient as
possible. I also have flow figures for a set of GN1 heads fully ported
by
Champion which compare almost identical to ours however they were flowed
on a
different bench so it would not be fair to post the results for
comparison
sake.We have a set of our ported heads on a stock block full weight car
that
has been down the track 4 passes and has run a best of 10.53 at 129.8 at
22#
of boost with mild launches, surely it will be a low 10 car at 130 plus.
I
have purchased about 7 sets of these heads and have had the same small
problem(s) with every set, however they dont leak and will run with the
M&A
head stock for stock( I have used them both) and they are priced right.
Just my .02
email me privately for more info.
Bill Anderson
P.S. this is the same bench that my Stage 2 heads flowed 345 on the int.
and
267 on the exh at 28 " and .700 lift so it does not read "light" in my
opinion.
