Used a set of these when you first sold them probably 10 yrs ago on 6.0L and surprised the hell out of everyone, made 643HP @ 7200 on E85 10.2:1 compression, talk about bang for buck, and yes when first got them was surprised at minimal material removed ( thought here we go been had) shipping to Australia was bit expensive but they turned out good value
88958758 for the complete cnc ls3 head but it is a discontinued part. I can't seem to find the bare cnc head but I believe it was offered at one point. Still going to be discontinued as GM has abandoned that line entirely now.
I like the SDPC videos like this, so I called SDPC today to order some cylinder heads. I have never spoken to a phone rep who was less helpful than I experienced today. Check out the videos, but buy your parts from folks who actually care - and its not SDPC, IMHO.
@WS6 Racing, We sincerely apologize for the way you were treated on the phone. It would mean a lot to us if you can reach out to us to find out more on what happened so this does not happen to any other customer in the future. Please contact Crosby @ 806-798-4000 EXT 304 or clong@scoggindickey.com
Know what's cool? I have to rebuild my engine now after buying these heads (gm performance ls3) because an intake valve decided it wanted to delete itself 100 miles after the install.
Yall give out some hella trove of LS education for free so me (the consumer) will buy from SDPC! What about the ones who are past the LS and spending $$$ on Gen V LT engines? Im 20 bricks in and not a single brick has gone to SDPC! or Holley, Edelbrock, Brodix, Dart!! How about a selection of fuel systems. Not only LT4 vehicles, but LT1 Silverados? In tank fuel pumps(E85,Meth) brushless systems with 70+ continuous pressure? Harnesses, regulators, filters? Etc. There are many of us frustrated late model owners waiting and waiting and waiting! Some driving our old stuff while the new stuff sits engineless because no one will fill the demand gap! I think the demand is greater in our great capital then it is from your bread and butter. The consumer! And the rest of yall are all doing the same thing! Sell outs man! Ya'll ain't in yesterday life today no more brah? "We" are! My money spends other places too. But anyway, great content guys.
Thank you very much! That explains a lot and is saving me money!

Cool and thanks 😎
What is the part # for the CNC LS3 head? Can you get a bare CNC casting also and if so what is that part #?

The new 632 big block RSX cylinder heads will those be available for purchase anytime soon?
They will be available at some point in time but we haven't heard anything on availability yet.
Ls7 heads fixed style?
You forgot the flow # ;)
