Any 318 Performance tips?

If it's this one or something similar, your good to go. As far as a minor cleanup of the heads, if you have time, it certainly wont hurt, but I'm not sure how much difference you'll feel on the street. A good valve job would be just as important from a performance standpoint in my opinion.

That's a nice cam for that combo.A good valve job,will live longer on the street ,long term. That "good valve job,bowl blend " will hit 5-600 bucks,with the existing parts.,upwards if worn . Feel the same tomorrow ,yes. See & feel the same 3 years later,not likely.
