Lets put it this way.. They would probably flow somewhere around 295-300cfm on the intake and around 225 on the exhaust.. Maybe more maybe less, but nowhere near 250/260cfm on the exhaust.. That just isnt going to happen..
Still good flow for the price tag on em tho!!

Not to mention the sweet cost effectiveness.
Brent, could you post the exhaust flow numbers please, for all us curious cats?

You are correct, to some degree. Every time I see a post like this it reminds me of what a poor job I have done to educate the consumer. We flow our exhaust ports WITH A PIPE. Exhaust flow with a pipe is a far better method to determine how efficient an exhaust port is.
Let's say we have 2 examples of exhaust ports flowed WITHOUT a pipe, one flows 250 @ 88cc, the other flows 230 @ 79cc. Now flow them both WITH A PIPE and let's say they both flow 260. Which exhaust port do you want? I will tell you which one will hands down run better, the smaller one. There is probably 30 cfm difference in OUR exhaust port WITH and WITHOUT a pipe, and as long as everyone understands this basic priciple, then every thing is great.
So bottom line is don't flow our head WITHOUT a pipe and compare it to someone else's exhaust port WITHOUT a pipe, ever. Hope this helps

Who said you guys didn't use a pipe? I'm just saying that the bench you guys use is a little different than the other benches used by AFR, Thunder, Patriot, Bennett Racing, etc etc.. And the bench you guys use normally shows numbers higher than what a SF600 or 1020 would show. And all of the smarter guys around here know what I'm talking about..
I never bashed the heads or said they weren't good.. The price is obviously great no doubt!! I believe that TEA does really good work, the flow numbers are just a lil different than most others that I've seen..

I dont think that cam matches well with these heads myself.
With a cam that big I would do a better set of heads and flycut the pistons.
If your gonna run a nasty cam might as well make the power to back up the sound. These heads will work better then stock, but a stage 2 5.3 or LS6 head or would be a better fin IMO.
As for the flow numbers.
The exhaust is BS from head porter to head porter.
I like the pipe idea as it is a more real world test. If a pipe is used then it would also be nice to see a LS6 or LSx intake used on the intake side to get a real world test as well.
Its to bad we dont all get together and determain a pipe that should be used to keep all the results as accurate as possible.
You simply cant have one company using a 10" straight pipe that is 2 5/8" big and compair it to another company using a 22" pipe bent like a header that is 1 7/8" big. As far as the number on the intake side, if JRP has seen 3% then that is damn good IMO. 330 CFM's minus 3% is still 320 CFM's at .600 and damn impressive.

Totally agree with that.. It would be nice if everyone used the same fixtures when testing these heads.. But, it would be nicer if everyone used the same benches!! lol (sf600 or 1020)

Only used a play-doh entrance. It is Z06 intake valves, I can't answer about the exhaust valves... Which valves are you talking about? A 1.60 or 1.62 valve maybe, but thats pretty tough from my experiences. They must be doing some great porting in there!
