Another late replyer...
HPE (aka Matt "Holeshot" Hobson) is doing 760 billet kits to go on a 62t case with stock stroke 701 crank. It will bolt straight to a 760 style case and with minimal work it fits a 701 62T case. Im waiting on my kit to arrive soon so I can put it through its paces.
New Billet 7 port cylinder jug
New 7 port sleeves
84mm wiseco pistons
Billet head
Billet domes
O rings
Exhaust gasket
Stainless head stud kit
Stainless girdle stud kit
Base gasket
Flow controll plate
This kit can also go to 809cc with the thicker base gasket he does and the port timing is still happy.
Not the best pic but this is what it'll look like
