how much stall?

I'd try this one https://www.summitracing.com/parts/cca-12-246-3 If you go with the 200-220 larger heads. Still can't beat a custom made cam.

I know as much as I can learn and try to keep an open mind to anything!

If I didn't overthink stuff I wouldn't be on speedtalk!

I would not use bigger cam than this one (maybe one step smaller) especially with the 220 heads and a stock stall converter - http://www.lunatipower.com/Product.aspx?id=2324

Or does this type of Cam ramp up the speeds so interference is Less likely
The peak valve lift has little to do with the valve to piston clearance VTP when the valves and piston gets close at near TDC during overlap. It all about duration and overlap not lift.

When the valves are full open max lift the piston is well down the bore not near the valves.

Duration, overlap and LSA effect VTP clearance, not peak lift.

When ever you are using a head with non OEM stock valve spacing/location always check VTP clearance yourself. Its up to you to check this.

In out of the box form the AFR's are the best choice. The World heads are solid heads when ported. Nice castings.
This is a example of a motor that could use intake port floor inserts. This will speed up the ports with minimum flow loss. ( if someone cared to do that.)

You want to check VTP clearance on this one. Just because.

are those the 2 heads you have? or are you buying new ones?
if new I would look at something around 170cc for the low rpm youre looking for.
220 head is pretty big for a 350 with no rpm, it would loose power everywhere.

Pocket port the Dart165s and use Mikes cam. Don't tell anyone how small the Dart heads are. Use the big heads on a 383 or 406.
