i WAS just wondering if anyone has ever heard of 32-valve aluminum heads for an LT-1 or Ls-1? If so that would be great...it would be interesting to see how much more power the 32v heads can put out against the 16valve heads. If anyone knows of anyone actually running 32 valve heads or about any company or manufacturer, please let me know! Thanks in advance.

Do a search on Advanced Tech for the words "Dominion" and "Arao"..... the same company. They have 32V heads available for the LT1. One of them supposedly flows over 400cfm.

There are two people with sets of the 350cfm heads, but niether has a running engine.

I've heard of 32V heads for the LT1, I think they are called "Dominion" heads, also heard they are very $$$.

Yea those heads are crazy... wish I could have them. You should check out Mindgame's car... he custom tailored his engine to accept GM 15* heads as compared to our 23* heads. Apparently the entry angle change was enough to give him over 550 rwhp and a 10.5 ET N/A... That's just beautiful.

32V heads so do you convert to DOHC? or is it still OHV?

I don't think they will convert it to a DOHC. Those 32v heads are just beautiful, by the way. $5200 though, that is a little too steep at this moment.

I didn't think it was a DOHC setup, didn't really see how that would be possible...just thought I'd get clarification.

The Dominion/Arao 32V heads are still "pushrod" actuated, from a single cam, in the stock location. One pushrod pushes up on a lever that operates 2 valves. The "shafts" on top of the engine are simply shafts for the rockers.

Thanks guys for the input. I checked the heads out and they look and sound great, but for the price im gonna have to wait and see what else comes out. Now that i remember, a couple of months ago, i heard of an LS-1 F-body with 32v heads. Im not sure if hes a member of this forum or another though. Anyways if anyone else has any other input let me know.
