So I was looking through the GM catalog, I see the DR head along with the DR head rockers and intake. I hope all these come out together. Just opened this to see if anyone has any new info on a release date for all this stuff.

Yeah, Cary can certianly relate to the difficulty if getting a new product out the door. It's not as easy as people think.

I have heard that they have cast and machined heads over the past several months. Not official but I was told that they have made a couple of small changes in the molds and the process to tweak the final version.

I keep hearing any day now but I have heard that for several months.

Soon very soon.....

Do we have another Street Wairror caper on our hands?

Robin L

Not even close. I have contacts at both and I can tell you that they are not even close to the same situation.

I have seen the new DR heads. They are real and they are fabulous

Someone I spoke with @ GM the other day said that they're not too far off. I'm looking forward to them, as I plan to utilize these and GM's intake with my new build

not that it pertains to the DR heads, but speaking in terms of catalog items...what's the status on the "LSX 454" valve covers? and where can we find images of the other valve covers not pictured in the catalog like the GM Performance Parts/LSX valve covers?

I would call Scoggin Dickey about the new parts in the catalog. I called them today and they had some of the LSX style stuff in stock.

Hey Robin, how would you compare these DR heads to a set of Edelbrock Victor LS-R heads done up by RFD?

+1 on this.

Robin L

Well the heads are apples and oranges. First the LSX DR heads are the top of the line inline valve head. The LSX-R head is a canted valve head.

Most top of the line inline heads will flow about 400 to 430+ CFM on the intake. They will be able to utilize a the 1.625" valve springs and will flow well past 1" of valve lift.

The canted valve heads will flow 430 and up depending on the port design. With the tilted or canted valves it is easier to get a better line of sight into the cylinder without the limitations found in a in line head. Also the valve location is more favorable to a piston that doesn't require deep valve reliefs at the edge of the piston over the ring land.

The Canted valve heads are VERY expensive and requied a lot of custom components such as valve train, intake manifold and custom headers. THe top of the line in line heads will require the same.

I have not seen any pricing on the LSX-R or the GMPP LSX DR heads.

The class that I run requires inline heads. I would have liked to try a set of the Edelbrock heads on an NA engine but that deal never came through. There are some people with builds in process so we should see some results in the next several months.

I remain cautiously optimistic that GMPP will get the DR heads on the market soon.

Thanks Robin. Got a chance to look at a edelbrock lsx-r head 2 day. WOW!! is a understatement as is the "PRICE" of the finished product. But I feel u will get what u pay for with this head.
