What heads are better for towing and plowing.

[cwilkie]

I am undecided on what type of heads to use when a 402bb & th400 are installed in my 1972 3/4 4x4. I plan on using the truck to do some light hauling, towing, and snow plowing. There will be occasional trips to the hardware store that that is about 120 miles away so I would like it to be drivable.

I have a set of casting number 292 open chamber heads and a set of casting number 063 closed chamber heads. I won't be hot rodding around but I do want some torque if needed.

Since a new 3/4 4x4 is around $40,000 I figure I would just spend a few thousand on upgrading mine and actaully own it instead of the bank owning it like they would a new one.
