Has anyone gotten their STOCK LS1, LS6 or LT1 heads flowbenched? I'm in search of the actual flow #'s in stock form. I've heard they flow in the 280's stock but, I've never seen them done.

 

2000 and up 5.7 heads flow 230cfm to 246cfm from .400" to .650" lift at 28". Earlier heads flow about 10 cfm less everywhere. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

 

Thanks. I called my porter kinda dude. He told me he's flowbenched several sets and they flow about 240 on average, when stock. I said, "COOL, thanks!" I had been told it was more several times. I only cared about intake side, since I just wanted to get an accurate answer. Anyway, thanks.
