coolant leak

[Paul Lennemann <pjlenn@xxxxxxxxx>]

Tonight I worked on some of the bugs that showed up after getting the 
engine in yesterday.  One of the problems was a couple of coolant leaks 
from the exhaust header bolts.  I was using bolts that were 1 1/2" long. 
 On a couple of the holes they bottomed out before getting tight.  So I 
got some shorter bolts and started with the last one on the back of the 
left head which had been leaking.  I found out that there are only @ 
1/2" or so of good threads as the shorter one would "strip out" when you 
started to get them tight. So I went back to the longer bolt which seems 
not to be too long in this case.  I slathered it up good with thread 
sealant and crossed my fingers.  If this continues to leak what are my 
options, heli coil or????  And if it needs a heli coil can that be done 
with the head on the motor, or does it need to come off?
