Sometimes things go my way. Got the new manifolds home, the junkyard didnt bother to ONLY sell me the exhaust side, so I got both. Quick check of the gasket seal between the In and Ex witha spray of carb cleaner, good! Go to remove the stub of the exhaust pipe they cut, took the nuts off with my fingers!
Mounted it all up and hit the ignition, comparable silence to the racket of before, all is well!
