Head Flow numbers Tell me what you think? I was looking at some used heads I was wondering what ya'll thought of the flow numbers he gave me in comparison to other heads out there.
I E
.100 66 55
.200 140 112
.300 210 163
.400 256 192
.500 291 213
.550 304 218
.600 307 222
I am looking for other flow numbers to compare to TIA!

Re: Head Flow numbers Tell me what you think? here are my TEA stage 1.5 5.3 heads with 11.1CR- Exhaust ----Intake
.100----51.7----70.2
.200----111.2---138.6
.300----167.6---201.1
.400----216.3---250.9
.500----248.0---282.5
.550----258.5---294.5
.600----265.6---302.2
those flows you have look like Absolute heads cause they have very high 400-550 flows.
dont just look at the flow numbers, check into how the have been performing at the track. They could flow there butt off but not have the velocity to match

Re: Head Flow numbers Tell me what you think? Well looking at The Farmers numbers I think the intake looks pretty good but the exhaust numbers are lacking. Is that something that is going to really keep me from running good or not I know that the exhaust does not have to flow as well because the velocity generated but are they really that bad for the street and a C2 cam?

Re: Head Flow numbers Tell me what you think? Inspector: the TEA exhaust numbers are with a pipe, so without the pipe they would flow around 230-240 I think. TEA just uses a pipe on there flows cause they like seeing how it would peform in real world(as on car).

Re: Head Flow numbers Tell me what you think? I'll have to get my wife to look for sure but I think it was 4.00 bore and 28lbs of h2o and SDPC did the flow so I am not sure what model the bench was until my wife calls me back and the valves were I 2.00 E 1.55 I think the intake volume was 243cc I will let you know when she calls me back at work.

My TEA 5.3 Stage II's flowed ~255 cfm on exhaust with a pipe. At the same lift without a pipe the heads flowed 200 cfm.
However, I think the valve job is really going to be more important than the flow numbers. The flow numbers don't tell the whole story.
BTW:I think if your going to flow exhaust with a pipe, the intake should be flowed with an intake...

Re: Head Flow numbers Tell me what you think? TEA stage 1.5 and 2.0 heads flow 220-224 exhaust max without a pipe. They flow 296 intake max. I was talking to the guys at Texas Speed and LS1 Speeed. Both flow tested the heads on there own.
