Oil leak at valve covers

Looks like these aren't to be used with your vc's?(gasket retention groove) As per Moroso instructions?
Our factory 273 Commando covers have that same groove. Let us know how they work out. I'd hate to spend that $$ and leak from the get go.
Thanks for posting Moroso instructions too

Moroso 93055 Gaskets on Stock Valve Covers. Currently torqued at 40"lbs. Installed Breather & PCV.
Generic Directions all makes and models from Moroso is 80"lbs for 1/4" thread fasteners. Seems like too much to me. FSM 40"lbs.
Have not run engine with new valve cover gaskets. Previous FelPro Cork gaskets were leaking, probably because of heat from HP manifolds.
