Default Anyone have head flow numbers for a non rev head?

Just wondering if anyone has ever put some stock VQ35DE heads on a flow bench. I am pretty sure that they flow pretty well for stock, but am looking for some numbers.

Thanks guys!

Pretty sure there is no difference between the rev and nonrev on this.

Edit: Nismo's website also has some info comparing their high compression cylinder head to stock.

Seems like from what the m2 site had and other guys that the stock heads flow between 270-280CFM. That is pretty damn good for stock!

The m2 race valve job has been bench tested to improve flow by about 10-15cfm so says their engineer who is a hell of a nice guy.

I'm just glad that the VQ35 heads flow so well. Didn't think they flowed that much stock.

I might not even get them ported lol.

well...flowing well and working well are to different things. I don't know your combo, but you could probably get away without porting, but they certainly pick up a bunch with proper machine work
