Heads are definitely a big part of making power, but compression & cam selection are important too.... Honestly these days I wouldn't put any money in stock heads... Trying to stick to the budget Bolt on a set of http://store.440source.com/Stealth-Aluminum-Cylinder-Head-COMPLETE-SINGLE-HEAD/productinfo/200%2D1055/ $1000 for a pair... Makes no sense to put $700 or more into a set of open chamber iron heads...
Summit has F/M rebuild kits with forged pistons, rings, bearings, oil pump, freeze plugs, etc all for $749....
When piston selection comes up make sure to select flat top with four notches... That gets you a good compression height...
That leaves a cam & machine work... Order this https://www.summitracing.com/parts/lun-10230703lk/overview/make/dodge & your cam is done... Leaves you $1000 for machine work....
You still need a timing chain set, pushrods & I'm sure I'm missing a few things but nothing big....
I'm not covering intake, carb, exhaust or ignition....
https://www.summitracing.com/parts/sum-g3511/overview/make/dodge Oil pan $95
https://www.summitracing.com/parts/sum-g3508/overview/make/dodge Oil pick up tube $20
https://www.summitracing.com/parts/cca-2109/overview/make/dodge Timing set $53
http://store.440source.com/Bolt-Kit-Cylinder-Head-12pt/productinfo/109%2D1514/ head bolts required because of the aluminum heads.. $59
Push rods need to be ordered based on a measured length but can range from $25 to more than $200.. For your needs I'd be looking at a $40-$50 set....
I'd expect to reuse the original rockers, Cheap aftermarkets aren't worth buying & good aftermarkets aren't in the budget...
WOW, this is exactly what I was looking for. Thank you for taking the time to put this together. I actually made a similar list and most of the parts I used for a budget build were some of the same parts you mention. The difference was the Eddy RPM heads here: https://www.summitracing.com/parts/edl-60929/overview/make/chrysler
I'm not sure if the Eddy heads are better than the Stealth heads but they are about $400 more.
I added up ALL the parts needed and there is no way the 3k will cut it. Here is the list I created. Let me know if I'm way off on any of these:
Machine Shop Work (Engine Hot Tank & Magnaflux) $250.00
Machine Shop Work (Bore, Hone, Engine Assembly) $1,300.00
Replace Cam, Rod, Main Bearings & Freeze Plugs $325.00
Oil Pan, Gaskets, Windage Tray, Bolts & Oil $300.00
Piston Kit (.030 over - 440source) $599.00
Edelbrock Power Pack (Heads, Cam, Intake, Lifters, Timing Chain, lifters & more) $2,200.00
Water Pump & Housing $150.00
Oil Pump $100.00
Power Steering Pump w/Reservoir $175.00
Fuel Pump $100.00
Harmonic Balancer $145.00
Crank, Water Pump & Power Steering Pulley $150.00
Miscellaneous Parts $300.00
Total $ $7,239.00
These aren't even the higher quality parts I wanted to go with such as the Trick Flow heads and the 440 Source Stroker Kit which would add another 4k to the total price.
