I think the i head with a stock 2.7 bottm end results in a lower
compression ratio due to larger combustion chambers?  Don't quote
me, maybe someone else can chime in on this.

Was that 180 at the wheels or calculated with a 15% drivetrain
loss?

If you want more hp get the head ported and a bigger cam maybe
a set of headers also-
