Just bought a pair of ej207 big port heads and upon arrival, I find out one of the spark plugs area has a small crack.
Doesn't seem like a major crack and during research I find out this is a common occurrence and safe to use as is IF the crack isn't too bad.
Anyone want to give their opinion on how bad is the crack?
Should I get it repaired? Not looking to make massive bhp, just around 400whp or less.

Thanks

 

very common and in general as long as it doesn't migrate into the valve seat are then they will be okay.........
