You can do a 383 or a 396 and you can use the GM heads on either but they need to be ported.
If you think you are going to build a larger cube bottomend and slap stock heads on it and get performance you are in for a very expensive lesson.
You throw even mildly ported heads on a 383 with a moderate aftermarket cam and what you will get is WEAK. One reputable vendor sells LT1 crate motors like this documented to only put down about 320-330rwhp. Personally I would call any heads and cam only without shortblock work that put down that little a failure, a stroker that only makes that is really sad. Aint the vendors fault though that his customers lack a basic understanding of how to make power, he just sell them what they want.
