Before I started making changes, I'd maximize what you already have.

1) fuel system. Make sure the sock in the tank isn't clogged, fuel pump is strong, any/all fuel filters are clean and the carburetor is clean and well adjusted. Clean air filter.

2) ignition system. Six good plug wires, six good properly gapped spark plugs, strong spark from the coil. Personally I go to HEI on every six I've owned. It makes them start and run remarkably better.

I'd bet you're down on power which is causing your frustration.
