440 Super Stealth head questions

[440beep]

Has anyone used the 440Source "Super Stealth" heads? If so, do they come with "default" settings for certain size valves? Or are the valve bowls pretty much left up to the purchaser for finishing size work?

I'm trying to figure out how much more work will need to be done to these heads, as the product description makes it seem like more work is required depending on what the purchaser's motor plans are.

TIA

I believe the site says they come blank but with seats which you have cut open to what ever size you want. Bowls are the same as the stealths at 80cc. But you can cut the valve out to 2.25. My dad was actually thinking of buying a set for his build. I went with edelbrocks max wedge victors just due to the build ill be doing and a company used them for a cnc program they are posted in the racer section fully cnc ported.

If he doesn't chime in, ask IQ52. He'll know.

Yea, my bad. Looking at the 440 Source website again, it doesn't look like the heads come prepped, but finalizing is left up to purchaser. Guess its ok because now my motor builder can do what he wants with the heads.

Sorry that this doesn't help anyone right now, but, we should have a pair of Super Stealth heads before too long. Finally we will have some real answers on what they are capable of.
