So I checked the compression on one cylinder it came out to be 145.... tested cylinder number 2 came out around 155 the car was cold didn't know if I needed a warm it up or not

Nice car! I've heard the "right way" to do a compression test is plugs out, throttle open, battery charged, engine to operating temp. I always do all the above, but usually the engine is cold.
145 to 155 seems ok, but I think you really need to test all 8, in the same conditions and go from there

I didn't do the Full Throttle open with that give a different reading I'll check them all
