Here
are the manifold cuts that I recommend. Use a bi-metal blade with either a hack
saw, saber saw or sawsall. Use plenty of oil.
This
manifold has ~20k but no cuts. It cracked on the bottom and the crack continued
to the turbo mounting on the top. Surprisingly there was no loud exhaust leak.
These pics are from my current manifold with over 35k &
4+ yrs old. 10-15psi
and some flogging.
