Head Crack

Wow....the San-Andreas Fault of cyclinder heads.... :blink:

I thought I heard spark plug holes were real bad place to crack, but not sure....we shall find out I guess....

I've had and seen lots of heads with these cracks, as long as the seat is in good condition, this is not a problem the crack normally doesn't go all the way up. I would worry about that plug hole being repaired more then that crack.

Couldnt resist :laugh:

Jay is right, NOS and Boost MAY enlarge the crack just a wee bit

I always get a chuckle out of that pic. Seen one like it of a nitrous motor when they added propylene oxide, they don't like each other! :laugh: :laugh: :laugh:

I was sure glad to read this last night! I had a bad moment when I found these:

The late Elmer Trett did that to 11 cylinder heads in a row and that was why we decided to do the billet head.

Hey guitargeek,

That is exactly like the crack in my 900 head.
