I just pulled the Berkley water logs off of my Olds.455...had some exhaust gaskets to replace, right? Well, my starboard manifold is got a crack the size of....well, you know. The Manifold is toast, cracked, major deformation on the the center two cylinder ports.
I need this problem resolved in 2 weeks as I will/should be on Lake Powell.
What are my options for bolt on replacements without changing too much else?
