I saw that you found something but also know that, us, car builders tend to change our mind quite often in these builds so I thought I would put it out there just in case...
I have a brand new set of Edelbrock SBC Aluminum heads part# 60719 that have never been even been mounted. More information on heads can be found here:

Jegs has them listed at $762.72 per head but I am willing to let these go for $1,000 + shipping. If interested, I can send pictures but they are brand new.
