World heads?

[zZsKyZz]

Does anyone have any feedback/info about the Iron WORLD heads?

I found a set with crane rockers for $350. Are they worth it and what do they compare to?

they are a decent set of heads once they're opened up a bit.

Couldn't think of what to compare them to though

One thing about used heads you always wanna consider

Can they be used just as they are
or
Do I need to sink more money in them

Things like ......

Do they need a valve job
Are the seals and guides OK
Do they need different springs
Do they need different rockers
etc etc etc

And of course with Iron ... You get no weight savings benefit

I know World heads have been around for a long time but thats all I know

I love my iron JR.'s and they are port matched to my Systemax and cheap horsepower. I picked mine up with comp valves, springs and scorpion rockers with guides for $600. Crazy deals like that on a lot of boards classifieds.
