Does not always play well with others
Cast iron intakes were bad about leaks too.
Not nearly as bad as the aluminum intakes. Cast iron intakes expand and contract at the same rate as the rest of the engine and thereby causing less stress on the intake gaskets.
The aluminum intakes expand and contract much faster than the heads and block and that leads to a much higher failure rate. GM put out a TSB regarding this problem on the TBI engines in the late '80's, early 90's. They even went as far as installing cast iron TBI intakes on the G vans in the early '90's.
