Hello, I just got my car back from the shop. I had the head repaired,
warp fixed and resurface. The head was presure tested and was found to
be fine. I also had all 16 lifters replaced. In addition, replaced all
of the head bolts. The car drives awsome, and sounds great. Wow, 16
valves can be quiet, and it has a lot more power. The only problem is
that I can see oil and smell gas in the coolant. The coolant had oil in
it before, although not gas. Could this be something residual? The shop
said that It could be associated with the fuel injection service that
was done? Is this a reasonable assumption? Should I be worried?

passages and crankcase are all exposed. Keeping everything out of everywhere
is difficult.

Maybe you can sweet-talk the shop into flushing the coolant. If not, don't
worry about it as long as the engine temperature is stable and everything
else about the engine operation is okay. There is no obvious way for
gasoline to get into the coolant after it is all assembled.. although that
doesn't mean it is impossible.

On the 740s/240s, it is fairly simple to drain/refill the coolant. The
instructions here are pretty easy to follow:

Also, this might be a good time to replace the thermostat, especially if
that hasn't been done recently.
