I see the 1977 delta only works for the 1977 model year. Have you looked on the edelbrock etc websites looking for the manifolds. What part of the manifold is leaking?"

Do you have any missing back out loosed up or broken bolts on the manifolds?I would remove the manifolds straight edge them if there not warped put them back on with new gaskets.

The most common reason for the exhaust manifolds to leak at the head is the bolts break loosen or back out. Let me know what you find.

Ok, one place called me saying they had olds manifolds. But it wont fit my chevy motor and I couldn't find out we're the Chevy 350 came from. If I take them off can I get them welded? Or what can I do?

The 350 is a stock engine size for that year I thiught they wernt cracked?If there not cracked why are you welding them?Its hard to weld cast iron when it cracks. You said it leaks where it meets the head that would mean warped manifold/loose backed out broken bolts. Thats why I suggested removing the manifolds and usuing a straight edge on them.

Heres another thing you can do if you cant find one clean up the metal around the crack really good. Then drill a small hole on each end of the crack to keep the crack from getting bigger. Then get some liquid steel it comes in a cup they sell it at auto zone. Use that to fill in the crack I used it before it works pretty good.
