Randy....I was looking at your signature and I see your engine is a 448(.040 over).. my 499 was a 448 and had StageVI heads, non maxwedge w/2.14 intakes...of course those heads have raised ports...and compared to maxwedge openings and runner size, they were tiny...but yet with a .557 cam, the Duster would rock...consistant 10.0 and occasional dip into the 9's..and that was when it weighed 3300lbs gross.. so what Im saying now after looking at your info, money probably better spent on the porting and flow correction, then get a cam specked to your flow numbers... or just can the heads and get bigger stuff...LOL

If i were you Randy, i would have Jeff mill .050 off the heads and try the 2" supersucker, i'm going to try one next year.

with the 2.190 intake valve you shroud the valve with a smaller bore,, it probably is a gain but usually we only do it with a 4.375 bore or bigger
at a 2.190 the intake valve seats completely on the exh seat where the seats interlock,, this may cause issues in the life on the valve job, though for a drag race car that you freshen every 200 runs or so its fine,, for a real street car,, i dont know if id do it

Ron..the answer to your question is YES...stock,re-conditioned rods and all! Brad,the answer to your question is also YES! I'm still looking for that "magical" $500.00 carburetor!   I REALLY do appreciate your very fair offer on the Demon RS...and you loaning it to me this past summer!   THANK YOU! After reading Jeff's comment...looks like the 2.14's are staying put!  After what I found when removing the rocker arm assembly....looks like a set of HEAVY DUTY pushrods are in order!  I'll post a pic a little later this evening!  I need to get some Play-Dough and check the piston-to-valve clearances to determine amount to mill for CR increase. Maybe 11.5 or 12:1...if allowable.  
At those compression ratios I think your going to
be getting away from pump gas(to me its not worth it)

Randy,
it looks like you are loseing the forest because of the trees.
flowing/porting your heads will tell you what you can have/make.then spend the coin on a cam and decent carb.
heck i just recammed a 440/512 and picked up near as 40hp with a still streetable solid.Dwayne Porter did dress up the heads a few years ago.
you may even want to look to your fuel system and suspension to pick up more et.
good luck

My  ... you won't notice the difference anywhere except for your bank balance. Unless Jeff K says differently (and his experience obviously far exceeds mine), your combination isn't going to see a significant benefit from a increase in valve size.
And if you don't spend the additional $$$ on bigger valves, that'll leave you w/ that much more $$$ to buy a new carburator (unless you've already made that purchase).
 Leave the 2.14's in there and save for a new carb
I'd also have MCH flow a few ports before & after to see what improvement you could/should expect with the cnc work

Well, I used big intake seats.
As I remember, the seat's already large enough for the 2.250 valve.

There are some good comparisons here...
http://users.erols.com/srweiss/tablehdc.htm#Chrysler_Big_Block
There ya go, there ya go! Look at the big increase in flows at the lower lifts. Even if 15% of the bigger valve sees a subtle increase in shrouding, it won't lessen the total flow in that area compared to the smaller valve, and if it did, other 85% of the larger valve more than makes up for it. And lets not hear that bologna about big valves lowering the port velocity and torque. The velocity will be controlled, in the greater part, by cubic inches and rpm vs the smallest sectional area of the port, not the valve size. You will see greater average torque with the bigger valve. Everytime we put in bigger valves we see power increases in 318's to 500's.

On all the RPM heads I have seen, the original intake insert is not big enough to contain the entire 2.25 valve. Therefore, you have to grind the seat for the intake valve into the exhaust seat insert, unless, you replace the intake insert with a larger one. The new intake insert does not interfere, with the exhaust valve seat area in the exhaust insert. Whew!

I'm glad I didn't take it down the track 1 more time,a few weeks ago! 
I might go visit Jeff K. first...I believe he's got a Rockwell hardness tester at his shop.
