To the OP, it seems like I read that the later version Schumachers fit the engine at the stock height, I think the old ones were the ones that set it up higher. Mine worked out fine( bought them in 2011) and my shaker clears the hood. One alternative on the valve covers is going to the original stamped steel V/C's , on mine, they clear ok and just require a little manipulation to remove. I'd rather have the aluminum also, but unless I do some fender mods, that won't happen. Good Luck!
