Hey guys .I had a head on the starboard side that had a water jacket cover bolt snap off and it cracked the little housing that the threads are in and I decided to just replace the whole head and the casting numbers are 332137. Do I have to keep that number or can I use a different number with the same year and model for the starboard side thanks for your help
