Ported LT1 Heads
These aren't majorly ported but they are a step up from stock, and the last car that they were on dyno'd 540 to the wheels with a procharger @12psi with a 224/236 cam, they still have stock valve's and have been cleaned, milled .010 and have dual coil springs that tested 120lbs seat pressure... anyways, flow #'s are...
Lift--------Int---------Ex
.100-------56---------42
.200------123---------90
.300------174--------123
.400------210--------147
.450------222--------153
.500------232--------158
.550------229--------163
.600------226--------167
The exhaust to intake ratio is almost right at 70% from .300 to .600... and with a 3-angle valve job and bigger valves they might reach 250/175
600$ shipped obo... I'm going to try to post some pics...

Re: Ported LT1 Heads

I'm sure with a 3-angle valve job they will flow a little better also...
PM me if interested.
