I need to put a bolt in the back of the head for the exhaust cross over. The pipe that goes to the H-pipe I think it is. Need to know size of bolt and thread size.

I believe spark plugs are actually the wrong size, but all the carbon makes them seem ok. Correct size is 5/8-11 IIRC.

It is a 5/8 11 course thread. Make sure to put some thread sealer on it.
