[DML] exhaust problem

[Soma576@xxxxxxx]

Hey Group,
 
I have my engine out and I am doing some exhaust work on it.  I have  
uploaded a file to the yahoogroups photo section under the folder '11596' for  you to 
view.  You can see that this port has me worried.  the bottom  left corner is 
dimpled in the aluminum and the upper left stud hole appears to  be corroded. 
 To my knowledge this port was not leaking but I am not 100%  sure. I pulled 
the engine because of a blown gasket on the other side of the  engine.  The 
only way this one was leaking is if it wasn't ticking while it  leaked which is 
what tipped me off to the other port which appears to be just  fine but was 
ticking like a tractor.  The stud hole is pitted until about  1/8" deep where 
the threads start.  
 
Should I be worried about this stuff?  What should I do/what CAN I  do?  At 
this point bringing the engine to a machine shop is a last resort.  I don't 
have a truck or cherry picker, but if I have no other option besides  pulling the 
head then that is what I might do.  I have never pulled a head  before, how 
difficult is that?
 
Any opinions or advice appreciated!
This project just keeps getting bigger and bigger!
