Well I pulled the head off my car cus it had water in the oil so I was thinking that I had a blown headgasket. I looked the headgasket over and it looks good(thats a bad thing

) so now I think I have a craked or warped head. I have a head from an 85 NA will that work. The engine is a JDM S/C 4agze w/ DLI
I think its the small port any1 know what head I can use and or where to get a good one??
thanks
