The question was from the point of view of a mild performance build using headers,camshaft,ignition,and carb tuning to extract every HP from the factory iron head with out porting.
Their are a lot of Olds fans that still like to play with the old iron heads.
The A head should have the ability to out perform the other heads in stock form based on that it flows more air. Of course the engine has to be built to extract the extra flow potential.

Mid Am was no secret if you really dig a little deeper it was posted maybe here on c.o. I know on Rop! After all the crashes on ROP maybe you never seen it! Mid am is gone thank god.

Some say the Edelbrock head is worth 50 hp out of the box.

I agree with you Bernhard. To the op you can port your own heads! There is a very good thread on how to do it on this site.

You said that the 330 engine does not run. Have you tried to get it started?
The reason I ask is if its a simple cheep fix you can get your car up and running. Then take your time planing and budgeting for future upgrades.
It could be something as cheep and easy as a timing chain, bad gas, points etc...

Well, something we can all seem to agree on. It just doesn't pay to pour money into iron heads unless there's a reason you need a certain iron heads for matching purposes. Aluminum is way cheaper and more bang for the buck and less weight.
Back in the day, I poured thousands into iron heads.
to wr1970, it's no big deal. I saw the 8 exclamation marks for 3 sentences, that is why commented. In the 1950s I was taught an exclamation mark represents "strong feelings." Jmo.

The small block is often over looked and responds well to basic engine mods.

I saw this on ebay and was wondering if anyone has any dealings with olds rocket parts, and thoughts on this set up seems to be a good deal

Mcolabella, I just saw you are in B-more. Shoot an email to Frank Trimble [email protected] . He'll fix ya right up. Straight shot down 95 to Beltsville.
Here's my Trimble bullet:
https://www.tapatalk.com/groups/realoldspower/pump-gas-468-t9139.html
1/4 mile math says it's just shy of 500hp at the wheels. I've been [email protected] so far; just need to figure out how to get it off the line and it should be mid 11s.

With the off shore heads most will tell you to buy bare casting and have someone that knows what they are doing build them.
A lot will tell you just buy the Edelbrock heads
Do searches on Classic Olds and real Oldspower this has been covered in the past.

Bernard, Joe Mondello's son and Cutlassefi, Mark Remmel both like and use Procomp heads. Problem is, the assembled in China version leaves a lot to be desired, which is what Olds Rocket Parts will be selling. Even with quality parts they come out cheaper than Edelbrock heads and you know it won't stick a valve or burn oil, they will give a long happy life on your motor.

So was wasting time looking around the net, and looking at the Harland Sharp rocker arms for the olds, noticed a few different part numbers and price ranges what are the difference between them
