Head and cam selection help for 440

I wish I'd seen this earlier, I have a 440 that we built in the 80s with 452 heads that makes 524hp and 545tq. It has an old purple shaft I believe it's the 5.57 lift mechanical, the heads are very well prepared with 2.14 and 1.81 valves pocket ported with 80 cc chambers for 9.5 cr..
I will repeat this was first built in 87 - 88 strait out of the old mopar engine book.
Just the cost of the valves retainers and keepers along with the springs never mind the hours of grinding is enough to make a set of new heads very attractive.
You don't say if your pistons are forged or not but if not your limited on RPM.
If I was building this or any other 440 today I would use the Trick Flow heads because I have never heard of having to spend money to fix a new set like all the others.
