Just send Ed an email. The chambers on these heads were custom made for my old 408. He can cut what ever you want.

So in order to run the heads I just need a new intake?

A ported FAST 92, Edelbrock Victor Jr or the new Performance Induction intake will fit.

What about something for the L98/LS3 square intake ports? Something for 1000hp+ would be nice :D

I currently have a victor jr so I might be able to pull the trigger on this:turbonaug however I think the ETP's flow better and just a few hundred more.

Also what are the limits on these heads? 1200-1500rwhp?

There is a limit but more with valvetrain and peripherals. BTW... we do carry the new version of the ET heads. re: Performance Induction. Email me and I can get a quote to you.
