83 Kawasaki GPZ 1100 engine INFO??

I know the crankshafts & tranny's are usable for early KZ cases.
83 Kawasaki GPZ 1100 engine.
My question is:
Is 83 , is it the desirable Bathtub Head??
Camshafts with peanut chain? To bolt in early KZ's also.
Just wondering? Local CL ad is parting one out

If it's a genuine 83 UNITRACK then it is a Bathtub head.
Cams use HYVO chain but will fit early motor with APE adaptor sprockets.
Tranny fits early cases with a fair bit of modification and special output bearing .
Crank drops in early cases but either centre pin needs swapping for MK2 one (easiest option) or major work to upper crank case etc to allow fitment of tensioner blades for HYVO chain.
Money is in the head and cams for most common desirable mods to early motors and 'J' upgrades.

Thanks Zed! This is what I'm questioning. It is buried in the parts section on Craigslist here local. I'm just looking to flip and make a profit. I knew the dragrace guys always used parts.

If you buy it I would be interested in the rear fender and maybe the fairing .
