Hey denmah, upon your tear down and rebuild did you happen to notice the rod orientation? As far as I know on those type rods the dimples on the rod all face towards the back of the engine. I think in your video when you show the little dot on the piston that faces forward, the dimple on the rod faces toward the rear. Just want to make sure because I have an engine to put together, it is my first LS build and I paid no attention whatsoever to rod orientation when I tore the thing down well over a year ago. Also, it is an L76 engine and has the floating wristpin rods and all. I think the big end of the rod is slightly different on either side of the rod as well, right where the cap is cracked from the factory. I think the side facing the front of the engine is bigger than the side facing the rear. Hope this makes sense?

are facing away from the dot on the piston. So yes they would face the rear
of the engine.

I thought you are suppose to set up a spring to the spec'd height that the spring manufacturer supplies with the springs.
I'm so clueless here . I plan on changing out my stock L92 intake valves (30K miles LY6 engine) for LS3 hollow stem valves. Do I need to do anything besides lapping the valves? FWIW Stock VVT cam and springs.
thanks,
Jim

I've never tried oven cleaner on heads before, but have had AWESOME results using Aircraft Paint Stripper on carbon deposits and such. If you try it, do not get the spray, get the jel in the can.
Thanks for all the good info over the years Matt.
