LS1 head flow numbers for my 84TA
(I am planning on putting an LS1 I bought into my 84TA).
Did some work on my LS1 heads at the machine shop yesterday.
Charlie has a Superflow head flow tester and I got all numbers at 28" and 77 degrees.
Intake Numbers:
Lift 0.1
Before: 61
After: 62
Lift: 0.2
Before: 129
After: 141
Lift: 0.3
Before: 189
After: 207
Lift: 0.4
Before: 221
After: 245
Lift: 0.5
Before: 227
After: 261
Lift: 0.6
Before: 227
After: 268
Exhaust Numbers:
Lift: 0.1
Before: 53
After: 54
Lift: 0.2
Before: 101
After: 111
Lift: 0.3
Before: 137
After: 151
Lift: 0.4
Before: 165
After: 188
Lift: 0.5
Before: 179
After: 212
Lift: 0.6
Before: 188
After: 224
These are with stock valves.
I wanted to get some pics but Charlie's digital camera is a POS and won't work in a low light condition. Give me some feedback! I was pretty pleased with the results myself!

Matt,
It looks like you have the information you need to size the cam, and lifts much over 0.500" will be a waste. I would try to find something that has a fairly aggressive ramp, lift to about 0.500", and a lot of duration over 0.300". I know the choices for LS1 engines are a bit limited, but a little homework here can really pay off.
You shouldn't have an trouble with flow on those heads - nice work!
