Oil puddeling on intake manifold .Factory 273 4bbl duel exhaust

my 67 273 2 brl. , I changed that single plane intake for a 73 model dual plane 2 brl. intake. All threads, male and female clean and dry. High temp red RTV was some brand other than Permatex from Oriellys, cost less. 3 or 4 years ago, I forget. One bolt now leaking/wicking in front of cross over on left side. That crossover area does get mighty hot on both sides. Good luck with yours.
