My coronet has the 318 granny motor in it. Nothing awesome, but I will be pulling it to regasket the thing (since it leaks from every possible place).

While it is out, I am afraid what I will find in regards to the 1969 castings.

Is the swap to the newer magnum heads worth it?

Should I use some iron ones I find from the local junkyard?

I will be running manifolds since it is a 4 door cruiser, but what are your experiences?

Yay or Nay? old small block heads or newer magnum castings??
