Timing I left up to my tuner.
Initially looked at running .040" gaskets but it the end I used factory .051".
Compression is close to 12:1.
Interested to see that your graph is a similar shape to mine.

On a DynoJet 248c it made 428rwhp before milling the heads.
All the tuning has been done on a Dyno Dynamics dyno.
Going by what it picked up on the Dyno Dynamics after the heads milled I would expect it to be around 440rwhp on a DynoJet.

Are you an automatic or manual? I would think 440 hp would be kind of low for a 12:1 motor. I've seen G8's that has like 10.8:1 compression pull 440 with Rick Crawford dragmaster cam.

Nearly all dyno figures from Australia appear to read lower the in the USA.
By weight shifted horsepower calculations I assume it makes 580-590 hp at the crank.
Car is 2001 Holden Monaro, similar to GTO.
Weighs 3,900lbs
4l60e with either 4,200rpm or 5,000+rpm converter.
Has gone 123+mph
