Whats the general feeling about these heads?
Seems like a hell of a price. Are they better than Iron Eagles?

I was sold on AFR 210's. But I may be assigned overseas for 4 years in the near future. Dont need a new set of AFR's sitting for 4 years.

All of the new iron heads flow about the same out of the box. If you are wanting to put them on your 406 I would have them fully ported. Then you will have a set of heads. Not a bad price. That is around what I paid for my iron eagles a while back.

Dirttrack winners swear by them, The rest of the pack swear at them.

The finish inside the ports are FAR SUPERIOR to Dart or World products castings.

I looked at the web site hhott71 posted. They have some good prices but to get good flow numbers you have to invest a lot of money in there heads. If you want to get the high flow numbers I would buy a set of their head for $850 and have them fully ported. Get the 2.08 intake valves. Then you will have a set of heads that flow better than what they listed for their fully ported and CNC'd heads. I believe it was under 300cfm on the intake and around 225cfm on the exhaust. With 2.08's you should be able to get 310-320 out of the intake. You would have around $1600-1700 in your heads and they wanted over $2000 for theirs.

Have a set of the CNC'd 220's on my sprint car and have not found a better head IMO yet. 99.5% ready to bolt on unlike the Iron Eagles. I had a set of Iron Eagles but they just didn't feel the same. Im actually buying a second set next week for the backup motor. Buy them bare and put them together yourself $$$.
