I just got a later model 235. The one with that has 4 stove bolts to hold the valve cover to the head.

Clutch is bolted to the flywheel and the clutch housing is still bolted to the engine. There are on the top two threaded housing holes and on the bottom two smooth holes.

Would it be good to secure the engine stand to the clutch housing?

Or will it make the engine to long making the engine stand unstable?

Should I remove the clutch housing first then attach the engine stand to the engine block?

I only see two bolts on the top of the clutch housing holding it to the engine block. Are there other bolts hidden? Or instead of having bolts near the bottom are there dowel pins?
Thanks Jeffrey
