CANFIELD! Anyways, that swap should work just fine. You'll need ARP head bolts #154-3605 for them though. The block has 7/16" head bolts, and the 351w heads have 1/2" holes. That bolt kit has litte "top hats" that slide on the bolt, and into the head bolt holes.
As far as intakes go, can't help much there unless you throw a carb on that thing, then I can help! LOL We had a set of ported E6 yes, E6! That made crazy power too! Didn't even use the better E7's and it was still rather impressive. Explorer (GT-40) and Lightning heads are a great junkyard find, so is the Lightning intake. At least that's what I'm told, I looked at one, couldn't find the carb, so I left it in the junkyard. LOL
