@zombezoo did you go for a set of the 440 source stealth heads ? Did you get the assembled heads with their valves / springs/ retainers ?

I bought directly from 440 source. They were assembled heads. Car runs much better. The engine had what were presumably the factory steel shim type gaskets. Between leaky valve seals and presumably bad valve sealing the car did not want to idle very well with the original heads. Its much...

...weeks and would like to make at least 1hp per cube. Stock 346 heads for now, I have headers but want to use HP manifolds for ease, 440 source heads next year. The smaller CC of those heads are being considered and would like to keep it under 9.5:1 with the 440 source heads. I get the stock...

I think you can get close enough to make you happy doing what you said you are willing to do. 451 flat top stroker from 440 Source, ported Stealth heads, 440 Source can probably tell you which of their cams to use with stock rockers. (I hate stock rockers, but I guess they will work for you.)...

...want some more compression. Just the flow increase alone will make more power everywhere. Just don't over cam it. I just pulled an 8.5-1 440 with the Comp XE274 out of my Duster. Changed from stock 452 heads to cnc ported 440 source heads I had lying around and it was a night and day...

If I do go that route, 440 Source will be happy. Stroker package, heads, rockers etc. Put together a low to mid range stump puller for my wagon.

I did 440 Source Stealth aluminum heads with a tunnel ram on a 383, 4 speed car. Extremely drivable, drive it all the time, mounds of torque for reasonable $.

I'd get some edelbrock small chamber E-Street heads, or maybe 440 source stealth heads. The better airflow and lighter weight will really help. Then just a bunch of tuning before deciding on the next change.

You'll get opinions on this that you may not like. Iron heads appeal to two types of people. CHEAP dudes and guys that are obligated to use them for specific racing classes. If someone is willing to pay even $100 for these heads, I'd be surprised. They are not rare and not hard to find. They are...

I think the 452's is the right answer for you. If you really want aluminum heads (they'll make more power than stock 452's, for sure) I'd revert to the 440 source stealth. In your research, study which heads have raised exhaust ports. Would be a nightmare for your situation.

470 stroker kit from 440 source, Edelbrock performer rpm heads, full roller engine, Edelbrock performer rpm intake, Edelbrock AVS2 850cfm carb, TTI headers, FBO complete ignition set up ( coil, ignition module, distributor) I have to look up cam specs

A molnar kit is about $600 more than 440 source. Trick flow heads are USA made. I’ve been told the quality is much higher.

I have a cast crank 76 440 in my 63. The PO had installed the very heavy speedpro 6 pack pistons I left them and installed a set of 440 source CNC Stealth heads, Isky 292 mega cam,RPM intake, Holley 750 double pumper,and Doug’s D452 headers. 3k converter and 373 gears. I’m very pleased with the...

...intake, 247 exhaust at .050 on a 110 center lobe. It will have around 10 to 10 1/2 compression. It had 10 to one compression with 440 source heads. The last engine I had in it had so much cam that the brakes would go out now and then. Or would an hydraulic cam be better? Any info I can get...

What changes for a hyd roller cam with 440 Source heads (other than hyd roller springs)? You say you would like to stay away from the needle bearing roller rockers. What's wrong with the 440 Source stainless, bushed roller rockers? I think they look great. (And the price is wonderful.) You only...

Spot on! A year ago .I started with bare block, factory crank and rods for a 440. After boring .030, 440 Source heads, Hughes can, JE Pistons, Doug's headers, Performer RPM, and a dyno tuned Holley.....and some other items WITH machining and the build ....10k. Oh, that also included the dyno pulls.

Just messing with you. I really don’t have any recommendations, but for something different I would look at 440 source first. I have had good luck with them for other parts and they are a very good company to deal with. I never heard of them until I joined this forum, and I gotta say they...

Guys what is your go to Valve Cover gasket on a bigblock engine. Mind you I run stock valve covers but on 440 source aluminum heads. I always use FelPro 1612 thick gaskets and a product that is really good for aluminum (Yama-Bond) or equivalent. I was having good luck but not everytime...
