Upon disassembly, it became evident my old log style manifolds have reached the end of their life span with issues far beyond leaking gaskets. That said, I've decided to replace them with more modern centerise manifolds for my 1969 302HM/Volvo application-- 2 questions:
- Anyone have a preference on replacement manifolds-- if so why?
- Also, I've seen some with one 1 bolt per cylinder flanges others with 2 bolts per cylinder-- can either be used?
