The head gasket gave indications of failing after about 8 months,
the motor had developed a slightly rough idle at low rpms.
Cold startups were also a bit off, as it took a few moments for
the high idle to 'kick in' and stabilize.
Initially I attributed it to possibly the headwork and larger valves
that were installed, but eventually I noticed a bit of oil in the
coolant reservoir which was a tell tale sign of a failed headgasket.
She had to wait months in que to be fixed, thank goodness for holiday
weekends.
Perhaps I should have retorqued it somewhere along the way?
Adding a Manual Boost controller helped speed up the failure
as boost was dialed in to just under 10 PSI.

I'm installing Mark's No-Blow gasket this time and will retorque after a few
100 miles and see how long this lasts.
Unfortunately, right after I retorqued the head back on after replacing the
gasket, I noticed something missing.

I found it lodged in an oil drain passage, and being I had replaced them
with stainless steel screws, a magnet was no help. It was a bit tricky
to fish it out. I checked all the other screws, which were loose and tightened
them to specs.
Interesting note, upon reassembly, I discovered the larger valves now makes
this an interference motor. I did not catch this the first time around.
Off and running. Got to do the axles next, that last jaunt earlier this year with
the guys in Ventura Canyon compromised the outer CV boots and made
a nasty mess in the wheelwells. Hope the weekend lasts..
