[Healeys] Sump gasket oil leak

[john spaur]

Ok.... So I might ask difficult, weird or anal questions at times but 
I still ask them so bear with me.

What are peoples experience with the stock oil pans versus the alloy 
ones and wether the alloy ones might be better at preventing an oil 
leak between the pan and block?

I know that if everything is perfect the stock pan is fine.

Does anyone have experiences to share?

TIA,
