On an old 306 i had I tried welding a big washer on top to reinforce the whole thing but it was a disaster. That few mill the engine was raised changed the whole geometry of the gear linkages and made it hard to get gears. Linkages would also pop off. Just incase anyone thought of this, dont bother lol.
EDIT found a pic on my old phone,
Dont do this lol
