Pull the valve cover off and take a picture of the number up close and from a little further away so we can see the push rod holes. Those two things will clear this up and send you down the right information hwy.
 
I’m thinking this is the probable number. They can be easily obscured by the rockers and springs, making it easy to miss the first and last number. Happens to a lot of us, even with experience. What year of 318 is it?
4323302 –318 LA-series small-block, 1.78/1.50 valves, Fast Burn, 56cc -65cc
 
Here's a couple of pics, don't know what year, it was in the car when bought.

They’re decent heads for entry level performance usage, but have their limitations. Commonly known as 302 heads/castings. There’s several threads about using those heads in performance builds. Factory equipment on 1986-1991/92 pre magnum LA 318 hydraulic roller small blocks.
Here’s a link to a member here who knows his way around with the factory iron heads.
