So I decided that it was time to try the heads from 440 source. I got them and honestly didnt expect much, and i wasnt disappointed. Yes it it a great idea to inspect anything you buy for any engine build. well, these heads have the cheapest retainers, Locks, spring cups, and valves. I took them to my machinist, hes doing a fresh valve job, gonna install new valves from hughes, springs matched to my cam spec, and touch up the horrible job of cutting the seats in, hone the guides, quite tight out of the box, install a better quality seal, and balance the new springs.
I will say the castings are vastly improved over the last set of Source heads I messed with. WAY cleaner, and way more professional looking.
I Will say this, for a grand, they are way worth the coin over sticking cash into a set of iron heads....

Did you miss the part where he replaced the valves, springs, seals and had the seats, guides and valve job worked on. He either has a lot more than a grand in these heads or a machinist that works for free and supplies free parts. Wish I had one of those.

In theory, there is no difference between theory and practice. In practice, there is.

Some people like quality. I know guys, I know.. its a street car, nothing hot, but i do like the stock look, i do like the affordability part, and im doing everything but the valve job, and spring balancing myself. i have 450 ish in parts, and machinist quoted me 275 for his stuff. i hate the squared off look of the trick flows or eddys, and the last set of eddys I had to basically do the same thing, valves were tight, springs didnt work for the cam, and i wanted things checked over. 100% only reason for this head was originality look under the hood. hell im running manifolds, so that tells you the build isnt too aggressive.

I’ll offer this counterpoint to the OP.......
Imo, The parts supplied with the heads are perfectly adequate for the primary buyer these were targeted at.
Used with a .500 lift or less hyd camshaft in an application that won’t need to exceed 5500rpm....... I see no need to replace anything. I just went through another set last week that are going on a very mild street 440 that will be getting the small summit cam, stock 4bbl intake, stock rockers, stock ex manifolds. They were less $$ than refurbishing the worn out factory heads.

EXACTLY where Im at, My 434 is a lil warmer then a stock 383. 440 crank, diamond pistons, decent set of rods from Hughes, and a Hughes cam. Im running Isky ductile iron rockers, and everything on this build is very very budget minded but I splurged on pistons, and rods.

My application is somewhat more radical than OP's engine but still only .652 lift and I won't be going over 6800 rpm. I started with a pair of bare Speedmasters that cost only $502... sent them to Dwayne and he corrected the Chinese valve job, did some bowl blending (Stage 1), and sold me decent valves. Now I have heads that flow 293 cfm for significantly less than Trick Flows which would also have to be at least "looked at". Reusing my low-use Comp springs. I wouldn't put ANY head on OOTB without at least checking guide clearance and installed height, and inspecting the valve seats

Did your machinist say what was wrong with the springs, retainers, or valves? The retainers were comp stuff for a long time, thats what came on mine, although I did switch them out for 10 degree stuff because I had the retainers. The springs that came on mine I’m 99% sure are Comp 911s.
My OOTB stealths made 479 RWHP and 492 RWTQ on pump gas, pretty good for a $1000 set of heads I thought.

Moparnut426 said: "i hate the squared off look of the trick flows or eddys, and the last set of eddys". Exactly! All other aluminum aftermarket heads machine the ends flat, machine in their logo and polish. The OEM look to many is desired plus its just stealthy and neat.
Keep old mopars alive.

Pretty hard to be-itch about a set of 1000.00 heads that flow 260cfm out of the box. Are most of these cheap aftermarket heads ready out of the box? No. They need checked over, maybe the valve job corrected (that will only lead to better flow and more horsepower) like others said I bought myself a good straightedge many years ago that I check decks, valves I trust but update retainers and keepers, and in any Head I check the valve guides. A little porting work they can easily go 300, and although I never pushed a set know they can go over 320cfm. Sure better than playing with 50 year old cast iron heads.

My OOTB stealths made 479 RWHP and 492 RWTQ on pump gas, pretty good for a $1000 set of heads I thought. these are definitely not comp retainers, and as or the springs, i just put the springs that Hughes speced out or the cam. they are PAC springs, and I had to call them to get the 10 degree locks and retainers. I hate calling in to hughes, they always get snotty with me as to why I want to change something in their "package" deals. I Just hate 7 degree chit!! period! I plan on running a rocker stand stud cause I've heard stories of the cast pedestals breaking off and the studs use full thread engagement. The spring cups, non swirl super cheap valves, roughness of the seats, and the retainers and locks just needed to be changed so I wouldn't cringe every time i gave her the onions...

They must have downgraded the hardware again, when I bought mine they had stickers on the boxes that said the locks and retainers were comp. Good to know.
And yeah, all of the Mopar specific places all seem to get a bit snotty about stuff...
