Ported LT4 Heads from Pace
Flow numbers are as Follow's...

Valve Dia.: 2.000" 1.550"
Lift Intake Exhaust
0.100 70.6 46.9
0.200 134.1 96.8
0.300 192.0 132.2
0.400 237.6 165.5

wtf?
you can get stock castings to out flow that. Flow isn't the end all but those are some downright embarassing numbers for comparitive purposed.
I promised seth i wouldn't post my flow numbers, but i can tell you right now LT1 castings outflow those on both intake, exhaust and it looks like midrange.

you can get bare LT4 heads for under $1k..........then get a MUCH better port job for less money, with larger valves.
trey, keep in mind those flow numbers are using stock valves, are yours larger?
also, its a CNC port job.......not a hand port.........CNC is for consistency, not to be the best hands down.
