LS3 head rebuild how to
Im looking to pick up some used LS3 heads. Plan to have a shop clean them up.
I dont know what all is needed in the way of machining them. I plan to put them on a ls2 with a LSA blower.
What tools are need? I understand Ill need to remove the rockers, compress the springs remove the caps. Install new springs and caps and reinstall the rockers. However the tools and how to do this I dont know.
I also have no idea what lifters and pushrods to use. I was thinking of getting a custom grind cam for the setup. Any help would be appreciated.

I just had a pair of 799 heads that I got back from the machine shop that, after checking their work, I am not too happy with. I could put together a short write up with pictures today if it would help you.

Send them to us.
Give us some $'s.
Wait a week or two and install your as new heads ready to go.
We use the O.E. rockers so going cathedral to rec port you will need a minimum of the 8 offset rockers and the other 8 if they have more than 50000 miles on them.
We also offer some nice rocker bars with ARP hardware for some more valve train stability.
We use the O.E. LS2/7 lifters.
As far as pushrod length goes you will need to mock that up to determine correct geometry. We can send you the ones we think will be closest but you will have to check.
We can set you up with a nice camshaft to compliment your package as well.

You could usually just drop the heads off at the machine shop for them to disassemble, clean, machine, and reassemble. If you prefer to assemble the heads yourself, which I would recommend, they'll usually give them back disassembled. This way, you can setup the springs for your cam yourself as well as check behind the machinist's work.
