7MGE Engine rebuild

No - head was in shop for cleaning and resurface then I took it back once all the valves were removed to do the porting. Then - back to the shop to have the valve seats done, valves installed, and then adjusted with shims. Total machine cost for the head was $450.

You want tot do the porting before the valve seats are done so you don't mess up the seats. Critical since they determine adjustment and timing.

If you really want to do it right and can afford the time - take both head and block to machine shop so both surfaces can be done clean.

Then new head gasket will be fine - remember I used studs and tourqued down to 90 ft-lbs.
