Slight thread hi-jack...
How do you remove these? Mine are stuck and when I tried to remove them the head started rounding off. When I had the machine shop rebuild the shortblock I asked them to replace them, but they 'forgot'. My father in law says the old trick is to replace the bolts with a marine style drain petcock so you never had to unscrew them again (not sure what do to on the road if they start leaking though).
