Brian,
It sounds like they were charging for labor AND parts for the guides
and seats. Your total was $184 for the above, but the cost (to me)
for the parts would be $98 (or so), so the effective cost of the labor
was a measly $86. Of course this does not include the resurfacing
of the block face of the head.
TRF charges$350 for a rebuilt head, and you have to pay shipping
twice (to send back the core). I guess the shipping might be $30
each way, so the cost if the new head is around $410. By my first
estimate, doing it yourself at $390. This is not a major savings, but
I included the cost of a set of new springs ($40), which TRF probably
does not.. If you are starting with your own head which is known to be
good, and a known good machinist, then you might be better off with
DIY rather than TRF. OTOH, TRF is not charging a huge markup on
their machine work. I gotta hand it to tham about that.

Remember higher compression will require higher octane gas.

The machine shop I went to charged my $8 each for parts/labor to replace
my guides with bronze guides.

They also charged $15 to replace and grind each valve seat.
