Default Dart 2 heads

Does anybody have specs/info for World products Dart 2 cylinder heads? I know the pair I have have the larger chamber (72cc?), are cast iron w/ straight plugs. Are these still a respectable head? Thanks B.

Think your mixing brands.
World doesn't make Dart heads ,Dart does.
Guessing by the chamber size these are SBC heads ,so would these be Sportsman II head's?

Years ago they called those heads Dart II, now they are called World Sportsman II. Most of them were 200cc intake chamber, and they are sure alot better than using a camel hump head.

They were Dart II when they came out in 1987 I think (cant remember the exact year)

They were designed by the owner of Dart and World , They were called Dart II Cylinder Heads

Later, I dont remember the year, Dart broke off from World (dont know which one called it an end) and the head was called the Sportsman II

Some information above for you

What is you application? Car specs? Engine Specs? What do you want from the engine?

Descent head, Can still have DARN GOOD numbers from them today

There are a few 327/350's out there making 600-650hp with ported Sportsman II heads

The exhaust side IMO is small for a performance head, only 4cc bigger than most stock heads

Yup - those are them. Bought them in 1990. Came in 2 chamber sizes - 65 & 72cc (or was it 76cc?) straight or angle plug. I still have the instruction sheet for them but no part #'s, chamber sizes & if they are worthy.

68 el camino

The heads are fully ported & polished, 2.02/1.60 valves - exhausts are undercut (kind of scares me).

4 bolt 383 small block. Weiand dual plane 8004 intake, q-jet carb. Crower hydraulic: 210/218 .421/.444 112 lobe seperation
Hedman headers - primary tube size unknown, 3" collectors, 2.5" exhaust w/ turbo mufflers.

350 trans. 2500 stall convertor, 3.73 12 bolt posi. Have a 700r4 sitting on the sideline.

The guy that did the heads for me picked two cams for me - I went with the conservitive cam because of smog at the time & it was my dailly driver. I know it's a small cam & there is some room for improvement. Can anybody run my #'s thru a dyno program?

Chris's thread http://www.chevelles.com/forums/showthread.php?t=307671 got me thinking. Cams (& heads) have come along way in the last 20 years & I wondered if these heads would keep up with a roller... Car is 95% street driven, been ahwile since it's been to the track.
I'd like a big flat torque curve, more HP & more choppy idle, but will work with an overdrive (i know cake & eat it too).
Thanks, B.

Just as an example, Pro-Filer 210's AS CAST made 580hp/540tq on a 406 with a 242 @.050 hyd roller built by Bryce @ Dr. J's Performance

Heads run $1,000 from Pro-Filer

However your heads will work good, I could see 450-480hp from them with a clean up port

My friend has the 64 cc version on his 355, and has gone 11.60's with them in an uncut 69 camaro. I think they are a good head.
