Waking Up a Turd

I wouldn’t worry too much yet about exactly what to do with it until you get it apart to see what you’re really working with.

Unless something has changed recently, I don’t think there are any LAX heads still available.
For a “budget” type of performance head, the Speedmasters are probably the best bang for the buck at the moment....... especially if they do the Black Friday sale this year.

Without reinventing the wheel, what pistons are in the motor, and what the actual CR they will yield with whatever heads you end up with will provide some direction for the cam choice.

That being said.......If the motor really has the 484 cam in it, it’s too big for what you’re trying to do.

The intake really has to go.
