One head pulled, the driver side.

found a broken/missing bolt on the rear exhaust.

I also assumed i had cast iron heads, they looked like cast iron until i got the intake off, I found shiny aluminum!

I'm going to need to deal with that bolt later... :thumbsdown:



neat thing is i never noticed any hint of an exhaust leak or tick.


My floor in the garage is also very slick, it's making things a pita...
:lewx4:


back to work.

Been using aluminum for the heads since around 2001.
