A/C COMPRESSOR SPECS

Are there any dimension differences between the 508 and the 708?
i have the saiden 708 and it is hitting my header.

508 is smaller it only has 5 pistons. Im assuming you have a pacesetter header because Ive heard those hit the ac compressor.

my header hits but im not sure what compressor i have. my header now has a small dent in it so it would clear.
