ALERT!! SOUND THE ALARM!!..
Awesome! Thanks for posting that.
Quick comparison looks like the main different I see between your C5622 and the ones pittsburghracer posted are around the oil feed holes for LA cylinder head oiling. I think that C5622 will for me as well. I will just have to give them a close look when they arrive, comparing the holes to my block and heads. Now I just have to hope they actually ship tomorrow.
