Best head to run is probably something like the Edelbrock RPM but perhaps it is the Stealth head if you want stock appearing and straight plugs or the Trick Flow head if you want to make power. There aren't very many situations where the best head to run is a cast iron stocker head.

What are HP iron heads? I've never heard of such a thing? HP blocks but not HP heads.

info I got from another member is the 67-440-2780915 heads with the 174 exhaust valves were considered HP heads as they were transitioning from the 516 head to the 906 heads

yes the 915 HP heads are unique, only made in 1967, and the early small chambers with the later 1.74" exhaust valves. most 1967 and earlier heads had the 1.60" exhaust valve. 1968 and later heads had 2.08"/1.74" and around 89 cc. the early heads can be easily enlarged to 1.74"

Go stealth heads.. 2.14"/ 1.81" valves, slightly larger ports, 80cc chambers, and oh ya aluminum.. the only way a purist will be able to tell it is an aftermarket head is the head bolts - they use ARP style reduced head bolts/studs
I wouldn't waste my time on Iron heads- you'll have $500 in machine work in them and that's the cost of 1 assembled stealth head.. spend $1,000 on the heads, and $500 or so having them checked out/setup.. you'll be miles ahead - plus 50lbs of weight off the front end!

yes, this is why a vendor at the last little mopar swap I was at had 8- 10 pairs of stock BB heads, all for $100 TOTAL! no joke. he hauled them home? lol
like he said, everyone is going to an alum head, just makes sense. unless YOU can do all the machine work on iron heads yourself.

Yup Stealth heads all the way!!!
They flow great and weigh light, got mine for about 1k, just had them looked at and the bottoms ground a bit...
They are sweet---vvv

If it's a budget deal and you think iron is cheaper, I'd say find a set of running heads someone is removing to upgrade, and run them. With a 383 and the available pistons - the open or closed chambers won;t make much of a difference. You can simply design the build to whatever you end up with. I wouldn't get cores with the thought that you can go through them and save money. To do them right you will spend. Or you will get them "less than right."

Exactly ^ I have KB400 .030" pistons in my 383.. those are a 5cc dome hyper piston

How many is too many?
Check your valve shrouding with the Stealths on the 383. Probably some flow to be gained with bore notching. I even do it on 440 and 400 blocks when I can spare the CCs. The head gasket will show you where...

^ I didn't do that to mine and still made 460hp with a baby cam
