I'm almost done getting together parts to do a cam swap in my L92 since giving up on the supercharger idea and I realized that I still have my 4,000 miles LS3 heads from my SS. I was thinking it would be great to get those down and I could clean them up and go ahead and swap the valve springs so when I do the cam swap it will save me a lot of time. Is there any reason NOT to use the LS3 heads? It's been my understanding over the years that they're the "same" head just the LS3 intake valve is sodium filled to save weight. I would only be doing this to save time during the swap, I know there's no performance benefit to it. I've been saving them because after losing my *** years ago selling a modified car I've kept everything from every car since and returned to stock before selling. I'm not planning on selling either of these vehicles any time soon and if I did, I'm sure it wouldn't be too hard to find another set of LS3 heads to put back on the SS or just leave the GMPP heads.
