Small Block head flow numbers

[JVMopar]

Does anyone have the flow numbers for a stock '302 head?

[Ray Bell]

What about flow numbers for aftermarket heads or modified heads?

They'd be interesting too...

Here's another site that's pretty good, has something like 1800 different heads of all makes.

That's a good comparison cause they both show about the same flow for the 302's without a tube.

Pretty generous numbers!

This site reminds me of engine weight charts...

I've seen some crazy engine weights, which are picked up from all over the place like these head flow numbers are (on this site). Problem is you don't know whether they're with or without flywheels, ancillaries etc. Apples and oranges.

Sure, they have the 28" of water etc. But they are coming from a wide range of sources. Is there much scope for them to be significantly out?

Ya but what's the alternative, build a engine, buy every head your thinking of getting, dyno them all then keep the best? Sites like that are just another tool you use when deciding what you want to get. Making a decision from any one source is foolish.

I believe tests at various alltitude/humidity/temp may vary?
