o dear, I have had the same problem too! remove the barrels,
very carefully, check the tappet blocks for any damage (where the pushrod seals fit) replace the tappet block 'o' rings, make sure everything is cleaned with thinners.
fit a new base gasket using Hylomar on both sides, refit every thing, run the engine untill it is hot, let it go cold overnight, retighten base nuts, cylinder head bolts, presto no oil leaks.
