Jet size

[classical glass]

I have a 427 side oiler stroker w/2 4160 600 holley 4 bbl. I have stock heads, MSD ign comp ratio is 10-1 with a Crower cam (16331) lift 551/565,Lob center 108, ford roller racing rockers 7-1 ratio. I sent the carbs out for a complete rebuilt and restoration to be sure everything was correct. I'm running #70 jets on primary/secondary on both carbs, #25 squirter. my plugs are a little on the dark sooty side (not oily).The car runs very strong no harsh smell when at idle and no exhaust smoke. My question is #70 jets a little much for this set up? My gas milage is almost zero, but who cares.
Thanks.

I forgot to mention my exhaust tips are black sooty not oily just black carbon you can wipe off with your finger. The heads have been recently gone over, harden seats, valves, springs, guides, seals etc.
