ISL Exhaust Manifold Leak - How far can I drive it?

Smitty77, consider yourself very fortunate to have found a decent shop.
I had a warped exhaust manifold replaced in Tucson and was hosed $2225 for labor and $767 for parts last APRIL. This did include time to replace a rusted drain valve on the rad found when attempting to drain the antifreeze and replacement of the coolant line from the head to the turbo which broke during removal. Only one broken bolt an cylinder 3 to extract.
