Cody,
If it was my car, I think I would have the existing head rebuilt, drop in
the 7A cam (although I think you are already running the cam, no?), and
ignore the bottom end. My reasoning it this: As far as you know, there is
nothing wrong with the bottom end, and these cars almost never have ring
issues. It's pretty hard to do a better job machining and assembling the
bottom end than the factory.
What is the advantage of the higher compression head? Won't you need to get
your chips re-programmed to back off timing advance to avoid pinging?
I'd spend the extra cash on an intercooler.
Tom

Hey Tom,
Car has about 151K miles on it. The loss is on the Exhaust
Valves. They "estimate" that it will cost around ~$3300+tax to do:
- Valve Job with exchange for Modified 7A head (Swain Coating)
- New Piston Rings and Lower Bearings (As with the increased compression
w/ new the head and good non-leaky valves...this may cause increase
blow-by on the OLD rings)...so one of those "while your in there" and
only adds another 500 bucks to the job or so
- Waterpump and timing belt
- ARP Head Bolts
- Metal Head Gasket
- Fluids
- Labor
The thing I am having a hard time to swallow (even more) is whether or
not I should do the larger rods for another $1000 but I don't have plans
to do any more engine mods besides a FMIC. Thoughts here guys?

Cody,
How many miles on your car? Where is the loss; leakdown should tell you
whether its intake or exhaust valves or if it is rings, right?
