I'm really surprised that the older KZ750 heads were not compatible. The Zephyr engine was nearly a carbon copy of the old KZ 738cc eight valve powerplant. Right down to the 66x54 bore and stroke.
You guys have me thinking now..... I'm going to check part numbers when I get a chance. The head I got on ebay was off a '92 ZR750 and just happened to be there at the right time plus the price was only $250. OEM ones listed on sites like Babbitts and Partzilla were over $2000 and of course weren't available. So I doubt I would have gone a different direction even if they are the same but it could pay off in the future.
I wish I could find a center stand for it. I've collected two off of ebay so far and neither one fits. In both cases the shipping was more than the part so not worth sending back. Might see if I can get a welder to modify one.
