I just got the heads pulled off my comp g. I took my heads to work cleaned them up in the parts washer . I then noticed 2 small cracks between the valves in one of my heads,this was the head and cylinder that coolant was making its way into #2&4 cylinders. I am going to order a remanufactured head from eBay. Both heads are the same to my knowledge any.ideas on headgaskets? Should I have the head checked before scraping it. Also any tips would be appreciated to prevent another coolant leak.
