Wait a minute...so you'd trade it in for an even more unreliable piece of $hit?


How do you have a blown cylinder head? what blew? head gasket or valve seat drop? rocker arms fail or lifters collapse?

I had brought it to a mechanic, and he put a spark plug in wrong and ruined the threading causing a gap and leakage.

I wouldn't replace the head over that...I'd JB Weld the offending plug into the hole or heli coil it first. It has 2 plugs per cylinder not like its a big deal if you have to only use one side.
