head and head cover gaskets, I think -- 2 gaskets? torque issue, possibly.

Yeah replaced both gaskets torqued to specs an in order

from earlier post:

Ok got it back together head,cylinders all look great good compression. Now the bad top cylinder is still pumping water got fire pull top plug no diff pull bottom she dies swap both coils out plug an cdi box. All new gaskets clean an torqued to manual specs. Lost did not see any cracks in walls or head?? Any body got any idea bout drop it in the river️

When you had it apart did you look real closely for any pin holes in the inner exhaust cover ???/

These models are bad about if overheated the aluminum casting will pull away from sleeve and cause water intrusion. Also a warped head or exhaust plate can cause this as posted earlier..If its the sleeve problem the block is junk..

All looked fine has not been hot. Pulled head back off laid a straight edge on it and found bout a 2 to 3/16 gap in center. Got it back flat and true give it another go. How could this happen an not been hot.

1/8" to 3/16" is a lot of material to remove...finding another head might be advisable...to warp that much I'd guess the top and bottom head bolts were over torqued or the center bolts were way under torqued
