Very cool build, been curious about the LS327's that are available from GM. Does the LS327 have a 24x or 58x reluctor wheel? And, if it's 58x, what brand inverter box do you plan to use?

Nice to see a sponser build up a 5.3L Looking forward to the results.

Also can't wait to see what these heads are capable of. When will customers be able to order them???

We thought it was time to break into the truck market!

3 employees here have modded daily driven 5.3 Trucks;
- One a 2010 VVT Cammed Silvy on Spray
- Another a LS6 Hotcammed 5.3 in a 98 RCSB
- And this one will make #3. We drive what we sell, what can I say!

We have 3 sets available for sale right now!!!

I wish more shops were steping up to this market. a few more questions about these heads.

1. Do you have to return a specific 5.3 / 4.8 casting??? I only ask because I noticed your part number contained 862... I am assuming thats the casting the port program is bassed on. How ever NNBS may contain a 799 casting wich is different port design from the 706/862 castings.

2. Will you accept the castech casted 706 Heads as long as they pressure check good before issuing the exchange credit??? I believe the ones from 03-05 were the ones with possible issues any thing 06 up should be ok but should be verified by pressure checking them first.

3. Is it possible to order a bare set of cnc ported heads with out any valve seat work??? The idea being that i would like to finish them with a different valve size.

That's going to be a pretty cool build. Can't wait to see the outcome of this. If I ever had the money I wanted to 5.3 test mule like this.

BTW thanks for the pictures. Will we get to see how much work was done in the bowl area on a bare set of heads???

1.) Any good 4.8/5.3 Heads will be accepted. Part # is actually SD8926C, no 862 in there.
2.) I will have to double check to make 100%, but I do know we will not issue credit on any head that is not a useable core.
3.) Bare CNC heads are available for $875.00 under part # SD8925B

Once I get a bare set, I'll snap some pics for ya. Everything I have right now are assembled.

Am I missing something? Why go through the hassle to swap in another 5.3 instead of a 6L? Put in a ls2. GTO guys are dynoing 370rwhp with just bolt ons and stock cam
