Is this a good candidate for magnum head conversion?

69 318 with the standard bolt ons.

Top end: Edlebrock performer intake, 600 holley, no headers (yet). Old rebuild, but limited miles since. Stock rebuild on the heads.

Bottom end: A bit of a mystery: rebuild was so long ago, I can't read the receipt from the machine shop anymore. It was bored 30 or 40 over, and is running the following cam

Stock 904 but replaced the rear end with a 3.55 suregrip.
Car is now a daily driver 200mi/week so I'm not looking to build a hot street car, just something a little more respectable.

Tons of threads out there with folks chatting about the various magnum conversion builds but I'm not looking to make 400hp, just want to wake this older engine up a bit. Is this a viable option or a waste of money

thx
Steve
