4v Head flow Numbers

[Grabber]

Does anyone have the numbers broken down for the 03/04 Head flow?

I have tried to search many a time here, and cannot find anything, nor can I find anything on Google.

I am trying to compared flow numbers from the 4V heads, to the 3V heads.

Thanks! :beer:

Still trying to verify:


B heads: Intake: 230 cfm at .500" of lift
Exhaust: 145 cfm at .500'' of lift

C heads: Intake: 225 cfm at .500" of lift
Exhaust: 145 cfm at .500’’ of lift.

03/04 heads: Intake: 233 cfm at .500" of lift
Exhaust: 168 cfm at .500 of lift

3Valve heads: Intake 223.2 cfm @ .500" lift
Exhaust: 148.2 cfm @ .500" lift

My MMR stage III heads with 1MM oversize SS valves. Flowed by an independent head porter that fixed the poor seating and head shaving done by MMR. He thought the high intake #s would have been 310 cfm with the correct inlet, and the exhaust #s are a little low without a flow tube.
