I personally like the eddys but I have a couple buddies that have stealths with no problems, and for the money stealths are hard to beat for street/strip. If you can afford it I would look at Indy heads,cost more but you get more....

I thought the Stealth's were closer to the regular Eddies?

Will your headers work with the angle plugs? MP Eddies are straight.

I don't remember what type of plugs the Stealths had. I saw some, didn't pay attention.

I have Stealths on my 440.Been on 2 years no problems.Power is just about the same.Either you need to have checked before install.They take a long reac plug like a SB.I changed springs retainers and keepers because I run .588 solid cam and 4 speed.Id get the ported if I bought them now.Mine have seen over 7K quite a few times.That and its street driven.Rocky

I think the Stealth head is a straight plug.
Just looked at a set up in the Twin cities
about a month ago. A shop up there says they
should make more power than a full ported 906,
452 ect. They just need some lite port work.
He was telling us, with a little clean up they
would make a good head on a mild 440 out of the
box.

Whatcha buildn!

The heads will make similar power. If your 906 heads are ported and in good shape stick with them. Budget the price of the heads plus $200 to $500 to have them gone through. DON'T put either head on your motor OTB, they will REQUIRE clean-up.

Stealths are straight plug.Look almost like a factory head if you paint them.Mine cost 200 at the machin shop to have them checked springs changed some clean up and back cut the valves.My machinist has been doing it for 35 years a one man shop and very particular.He liked what he saw.Rocky

In stock, $899/set form, they will not work as well as an Eddy. However, for the money you can't beat the CNC'd version - these outperform Indy EZ1's which are a bit more money. However, the CNC'd Stealth's are at their limit whereas the Indy's still have a lot left in them. I bought Indy's - should have bought the Stealths.

Check the 440Source website - I'm pretty sure they're an angled plug.

stock 906's peak flow ~220-230cfm (about the same as a stock X head), stealths are in the 260-270 range, and eddies are in the 270-280 range.
