5.9MAGNUM EXH MANIFOLDS

Putting together a 273/4bbl, 340 spec solid cam, high compression motor for a '65 Dart. Was thinking of using the magnum factory style exhaust manifolds. Good idea? Need the magnum bolt kit or just use the LA studs/bolts?

I can not answer your question about how to fasten them. I can tell you fitment is an issue. Do a search. The subject has been beat to death. P/S and manual trans seems to be the biggest issue.
