Finally the 66 Dart is here!!

Well I,ve come to the conclusion that the slant is going to be a P.A.S!The headers are leaking at the head and I tried to fix the leak(header flanges are warped)on and off # times and they,re still leaking.I also took them to machine shop to be plained.They are just to far gone.Was gonna look into getting Dutra duals,but for that price plus shipping to Canada from Cali. $$ I,ve decided I can buy a running 60,000 mile 360 out of a Ramcharger for $300.So now I,ll need advise from early-A guys on this swap.I have a bunch of V8 stuff already,800cfm thermoquad,torker2 intake,elec. dizzy,wire,rad,tranny(904)d.shafts.Where is the best place and deal for conv. kit?M.mounts,headers.What else do I need?Any help will really be appreciated.Thanks.
