My 440 Source Stealth heads have arrived

[Hot_Rodder]

After waiting a while for my heads to come in from Modern Cylinder Head, I can finally say they have arrived, and I'm pretty happy. Here's some pic's:

Looks good... Exactly what did you have done to them... those are some nice flow numbers on the intake

Modern does nice work. 

Those will make some power with the right combo

Anybody know if any MCH stealths have been dyno'd?  I've been on the verge of having my setup ready to dyno for several months now, but now I'm not sure i'll have the extra $$ available to actually go through with it

Heads look great... should make some onions...what camshaft are you going to use ?

Work done to the heads:
Brand New set of Stealth heads, fully checked, intake ports taken to max wedge ports, exhaust ports fully ported, had the original springs/retainers/locks removed and replaced with 11/32 10* comp cams valve locks, 1.550 steel 10* comp cams retainers, and comp cams 1.550 street roller springs. Also they cut intake and exhaust seats and grind plus backcut valves, cleanup mill chamber volume (left to 85 cc's, with a flat top I'm going to be at 10.7:1 compression), then of course they washed and assembled them. Total price... We want go there, lol. The valve springs in this case were installed at 1.900" install height, 240 lbs, 575 lbs @ .650" lift, and 1.150 coil bind height.

I'm sure there have been dyno's done with heads similar to these, but I've not seen them so far.

I'm going to be going with an Indy Cylinder Head dual plane intake ported to max wedge intake ports, but I've not made up my mind if I'm going 4150 or 4500 yet, so....

The cam will be a custom solid roller done by a guy named Dan down in south Florida.

YOU ARE GOING TO LOVE THAT INDY DUAL PLANE.

[Hot_Rodder]

Yeah, I hear it's the biggest dual plane on the market for these Mopars.... I've still not made up my mind on carbs, but I'm leaning toward two different cfm rated carbs, both of which are 4150 style Proforms, one a 950 and the other 1050.
Here's a quick link, well.... possibly three....
The 1050: http://www.proformparts.com/mistore/productdisplay.php?sku=1034384&hdwt=31101&loc=101&dealer=no&company_id=100719
The 950: http://www.proformparts.com/mistore/productdisplay.php?sku=515838&hdwt=31101&loc=101&dealer=no&company_id=100719

Any comments?

how big is the motor? i use 1000 cfm double pumpers on my 500"motors.

[Hot_Rodder]

Will be a 505. So I'm leaning for sure to this one:
