Should I change heads?

[Accelo]

I would retain what you have if the only option was the camel hump heads.
If I changed heads it would be to the Vortec heads. They have stellite valve and hardened seats plus flow a bunch better than the antique camel hump heads.
The also require center bolt valve covers that don't leak and a different intake.
It will increase power over what you have.
I can see no reason to run the old heads unless you are restoring a truck.
