don't forget t make sure your pistons valve reliefs will handle the 2.190 valve radially. some do, some don't.

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

I'd call Patrick and get you a tweaked Pro-Systems 1000hp 4150, I have 2 of them (one on my 517BB and one on my 414SB) and they are night and day over an OOTB unit for not much more $$$. As said the 2.19 will tend to pick up the mid range and on a big block they would typically have a similar effect on torque to running a 4-8 degree larger @.200 duration cam. The gains on a conventional height BB port tend to be limited by the short turn and low runner height, not to mention the relatively poor valve to piston wall (shrouding) clearance, so a bigger valve doesn't always help as much (% gain) on a BB standard port head as you might see with a raised port Max Wedge. I've run 2.25's in an old set of 67' 915's but it was tight and if I didn't notch the bores I doubt it would have helped at all over a 2.19.

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

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!

Pump gas eddie headed 451? Pushing 800 horsepower? I say b.s.
Okay, that is understandable. As I look at it, I did make a mistake. This dyno run shows a beginning of 4,000 rpm, my apologies. I can produce other dyno sheets of 3,100-7,200 with torque above 500 lb-ft from 3,500-7,200 rpm and peaks over 600 lb-ft.
The engine ran in the 2009 Mopar Muscle Magazine Engine Challenge at 600 rpm/sec (less load on the engine) and pulling a mechanical water pump. On an exhibition run after the Challenge, it made 726 HP @ 7,600 RPM and 723.4 HP @ 7,000 RPM during the Challenge. See the May, 2010 issue for a brief build description.
The pull below was months later at 300 rpm/sec with an electric waterpump and with a better air inlet to the carburetor. At Comp Cams, during the Challenge, there was no air hat on the carburetor and the air was swirling around the dyno room like crazy. Also on this run we were using a different cam with a little less duration and a little more lift.
We made 18 dyno runs this session with various headers, tunes and loads on the engine and never made less than 743 HP and 13 runs over 770 HP.
The dyno is no longer a Childress dyno, but is owned and run by Aldon Miller of Performance Machine, Idaho Falls, ID. They just never could get the computer to change the heading.

Stir away!
They really are pretty good heads. On Comp Cam's dyno, everyone had to run the RPM heads. The only engine to beat us was 48 ci bigger. He beat us by 1.1 horsepower, 724.5 HP to 723.4 HP.
The Performance Machine dyno sits at 4,700' elevation, so that D.A. is very possible.
The next time I get a big hp/ci motor together, I'll announce it. We'll stand and deliver that baby, heads up, anywhere.

That is a possibility.
But normal D.A.? Gotta laugh at that one. Normal here is 6000+. You guys are the abnormal ones.
Comp is at 258' elevation and the correction factor should be much less. If the iron headed motor hadn't got toasted at Comp Cams this year (they don't run long if you forget the water), we could have taken it to the I.F. dyno and checked that theory out.
Tough to race dynos.

It's a real shame what happened to your motor, it's always nice to see these numbers translated to track figures, Brett Miller's car is turning some good times and sounds real sharp, it's quite amazing how much power some of these small blocks produce and with a lot less weight in the right place.

Have ANY of you done this?...what were the results?...GOOD,or BAD. Thanks in advance,guys! 
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.
