Some questions get quick responses, others... not so much!
I'll do what I can. In most cases, the cork that you cuss at is actually a decent gasket. What contributes to its failure? OVERtightened bolts, bent oil pan gasket rails and excessive RTV sealant. When I rebuild an engine and use an old pan, I always use a straightedge to check integrity of the pan rail. Valve covers are no different. The mounting holes are often pushed inward, requiring a few taps with the FORD tools to drive them flat again. I just did an oil pan gasket in a 440 in a truck. I wiped a very thin smear of Mopar RTV on the pan rail, set the gasket then set the pan on a table to press the gasket flat overnight. It sealed up like factory stock, maybe even better than. Small blocks have a different design, I'm aware. They tend to leak at the corners. A small dab of RTV during install is preventative insurance there.
I LIKE your screen name... Pretty cool.

So with the matching 360 oil pan that will work ?

Oil pan isnt the nicest but it is flat, straight and true along the edges. I have taken a socket & hammer and redone each bolt hole if it was pulled in. Cant say it didnt hurt but I dont think it really was the root cause. One of the issues I have had with presticking the cork gaskets is they will get torn up when reinstalling the pan. In the Van chassis atleast it is a very tight fit between the oil pan, crossmember and bellhousing (727). So after dropping the bolts and cracking the pan loose and pulling the rear of the pan down to work it out the front bottom of the pan is already dragging on the cross member and the front top end of the pan is dragging along the block rails for a few inches. Go to reinstall and that cork gasket gets torn up during the dragging. Maybe some fresh motor mounts would be the cure here ? God knows there probably original and with all the oil this thing has leaked for years they are probably due for replacement.
