it will start but not run, and occasionally would backfire out of the intake. like a small pop and a lil puff of smoke would come out.
-LS6 243 heads, i bought these heads and then had them cleaned up and a valve job done, with dual titanium patriot gold springs and ti retainers and new seals
-comp cams custom 234,236 11+4 lsa .580 lift cam
-7.400 hardened trickflow pushrods
-LS2 Timing chain
-Ls6 intake
-ls6 oil pump

The book calls for the pins for crank to be at 12 O'clock and the cam at 6 O'clock basically having them close to each other.
I think when I did this part I had the motor upside down and can't recall if I corrected for that and they might be reversed facing away from each other.
Here is a pic of the proper way
