What kinds of numbers are any of you guys getting full porting a 906 head and still using the 2.08/1.74 valves?

I have a 906 that I have spent a lil time on 2 ports, I still need to do a valve job yet...but so far with brand new valve '2.08' im getting [email protected] lift

They peak just under .550 and flow ginormous in the low lift...

So what do you guys get?

You must have ported the crap out of them, I got 268 @ 550 with a 2.08 valve 906s & they were still strong at 600+ lift., The mopar guy who flowed them was quit impressed for a port job from a 1st. timer, The exhaust was in the mid-upper 1.90s @ 550 & still strong at .600

Not that i'm bragging (well maybe a little) but those heads went 123+ mph at 3100 lbs. race weight with a small solid, the guy who has it now installed a .590 & raised the shift points & alittle steeper gear, he's a big guy, the race weight with him was right around 3300 lbs., he ran 125 mph with 3 weak cylinders, by the 3rd. run it was smoking, but heck, those rings had a good 300 hard passes on them.
