Exclamation TEA 2.5 on a 853 casting?

I am looking at these heads. He says that they are 853 casting tea stage 2.5. But on tea's web site there is only a stage 2.5 for the 243 casting. He says that the flow numbers are 309 @ .600 and 264 exhaust. Is this legit?

Sounds about right. Call the TEA guys to confirm just to be sure.
Their website doesn't list a few of their options, so 853 castings are possible.

You can run the 2.5 program on a 6.0 heads. Same basic port as the 243's. I've seen a few people with them.

It shows it for the 6.0 but not for the 853 casting. It just emailed them so hopefully I will know by tomorrow morning.

Sorry, thought the 853's were 6.0 heads. I don't get into casting numbers very often.
